Abstract :
Metal-nitrogen co-doped composite (M-N-C) carbon materials exhibit outstanding catalytic performance in oxygen reduction reactions (ORR), making them promising candidates to replace commercial Pt/C catalysts. However, it remains a challenge to achieve a rational design that ensures a uniform dispersion of the metal active centers in the nitrogen-doped carbon materials and an effective construction of the M-N active sites to enhance the ORR performance. This research introduces an innovative in situ pyrolysis technique utilizing the guanine biomolecule in conjunction with ZIF-67. This approach not only circumvents the pitfalls of structural disintegration and cobalt center agglomeration but also creates an abundance of anchoring sites conducive to the atomic dispersion of cobalt. Consequently, this method fosters the synthesis of Co-N and pyridinic-N active sites, which are pivotal for catalytic activity. The G-Co@NC-800 catalyst demonstrates exceptional ORR catalytic prowess, with a half-wave potential of 0.83 V (vs RHE) and a current density of -5.1 mAcm-2, coupled with remarkable stability and methanol tolerance in alkaline media. These attributes surpass those of commercial Pt/C catalysts, underscoring the superiority of this novel catalyst. This pioneering approach promotes the rational design of uniformly dispersed Co nanoparticles and the extensive construction of Co-N sites. Metal-nitrogen co-doped carbon materials are synthesized via a simple and facile in-situ pyrolysis strategy from biomolecules guanine with ZIF-67.The guanine transferred into 2D carbon nanosheets and nanotubes after pyrolysis, which inhibits the structural collapse and Co centers agglomeration of ZIF-67 during pyrolysis.The guanine provides anchoring sites for the Co nanoparticles (Co-Nx).The uniformly dispersed Co nanoparticles, as well as the widely constructed Co-Nx, provide a large number of active centers for catalytic activity of ORR in alkaline conditions.

Abstract :
Photocatalytic hydrogen evolution presents a sustainable method for clean energy generation, yet its efficiency remains limited by insufficient charge separation and transfer. Herein, we report a novel strategy to enhance photocatalytic efficiency by integrating both bulk and surface electric fields within self-assembled supramolecular photocatalyst. We synthesized perylene 3,4-dicarboxylic acid (PDA) with a large dipole moment and polar carboxyl groups, which self-assembles into ultrathin 2D nanosheets in water. The accumulation of dipole moments induces a bulk electric field, enabling ultrafast exciton dissociation into free charges. Concurrently, the exposed carboxyl groups generate a surface electric field, facilitating efficient charge extraction and transfer on the surface for proton reduction. The synergistic interplay between bulk and surface electric fields results in an impressive photocatalytic hydrogen production rate of 3.2 mmol g⁻¹ h⁻¹, significantly surpassing that of the other perylene-based nanosheets relying solely on either bulk or surface electric fields. This study offers valuable insights into the distinct roles of bulk and surface electric fields in photocatalytic processes, and introduces a new design paradigm for photocatalysts to enhance solar-to-hydrogen conversion efficiency. © 2025 Elsevier B.V.

Abstract :
MXene species have emerged as a class of compelling electrode materials in the field of capacitive deionization (CDI). However, as an excellent member of the MXene family, the Nb4C3Tx has not received much attention in terms of CDI. Herein, we have not only established the feasibility of Nb4C3Tx as a potential desalination electrode materiel but also proposed a wrinkle-engineering strategy that can effectively improve the CDI performance of Nb4C3Tx freestanding membranes. Specifically, the introduction of wrinkles on Nb4C3Tx nanosheets contributes to optimizing the interlayer space, accessibility, conductivity, stability, and CDI performance of the assembled membranes. In particular, the optimized wrinkled Nb4C3Tx membranes can achieve an ultrahigh desalination capacity of similar to 188.2 mg g(-1) at 1.6 V accompanied by a fast adsorption rate of similar to 12.6mg g(-1) min(-1), showing great competitiveness with other MXene individual electrodes. In addition, the as-designed electrodes also exhibit superior cycle desalination stability as well as good applicability to different salts (such as LiCl, KCl, CaCl2, and MgCl2). This work both extends the MXene material applicable to CDI and offers an effective solution for improving the properties of Nb4C3Tx-MXene lamellar membrane electrodes, opening up enormous opportunities for the use of such MXene species in the field of electrochemical desalination.

Abstract :
Photocatalytic water splitting on metal oxides often faces oxygen evolution inefficiency, reflecting the complex interplay of its two half-reactions. Strategies like heterojunctions, cocatalyst loading, or noble metal nano- particles addition have been explored to address this. Using gamma- Ga 2 O 3 nanosheets as a model, we uncovered the formation of-O-O- species as the key barrier to stoichiometric splitting. To tackle this, a strategy was devised, Sr-doping to inhibit surface peroxidation. The resultant Sr-doped gamma- Ga 2 O 3 (Sr-Ga2O3) significantly improved activity and stability, achieving balanced H2 and O2 production under 125 W mercury lamp light. Upon further enhancement with Rh/Cr2O3 cocatalyst via photoreduction, the Sr-Ga2O3/(Rh/Cr2O3) composite demonstrated a remarkable 173.3 mu mol & sdot;h-1 H2 and 86.7 mu mol & sdot;h-1 O2 evolution rate, 8.0 times higher than gamma- Ga 2 O 3 alone, with a 34.1 % quantum efficiency under 260 nm light. This represents a record performance for Ga2O3-based photo- catalytic water splitting. Mechanistically, Sr doping alters surface chemistry to favor direct oxygen release. Our study elucidates molecular-level insights into non-stoichiometric splitting mechanisms and offers a potent strategy to boost metal oxide photocatalysts' water-splitting efficiency.

Abstract :
The persistent threats posed by toxic chemical warfare agents (CWAs) such as mustard gas (bis(2-chloroethyl) sulfide, HD) and bacterial contaminants demand the development of innovative, sustainable mitigation strategies. Photocatalytic processes that generate reactive oxygen species (ROS) offer a promising dual-functional approach for both chemical detoxification and antibacterial defense. In this study, two structurally analogous covalent organic frameworks (COFs), BPY-COF and BD-COF, are synthesized using benzotrithiophene as the donor unit paired with bipyridine and biphenyl, respectively. These COFs exhibit high crystallinity, broad-spectrum light absorption, and efficient charge carrier transport, with BPY-COF demonstrating superior performance due to the incorporation of heteroatoms. BPY-COF achieved ultrafast detoxification of the mustard gas simulant 2-chloroethyl ethyl sulfide (CEES) with a half-life of 35 min and 100% selectivity for 2-chloroethyl sulfoxide (CEESO) under white LED light, outperforming BD-COF. Additionally, electrospun composite fibers containing 40 wt.% BPY-COF maintained comparable CEES degradation rates and exhibited over 99% antibacterial efficiency against Escherichia coli and Bacillus subtilis within 60 min. These findings highlight the potential of BPY-COF as a multifunctional photocatalyst for integrated applications in chemical detoxification and antibacterial defense, addressing critical challenges in public health and safety.

Abstract :
This work proposes a sigma-pi hyperconjugation strategy to establish interlayer charge transport channels (CTC) in supramolecular organic nanostructures. A series of ullazine-based molecular semiconductors were designed and synthesized successfully by engineering end groups to demonstrate the sigma-pi hyperconjugation that unlocks the quantum confinement of photogenerated charges in pi-conjugated planes. Ullazine grafted with tert-butyl (U-t-Bu) showed a J-cross-stacking model in which the cross-stacked U-t-Bu molecular pair smoothly glides along the elongated dimension, forming a Z-schemed interlayer CTC by sigma-pi hyperconjugations between C-H sigma-bonds of tert-butyl end group and pi-bonds of ullazines in adjacent layers along the stacking dimension. Consequently, upon photoexcitation of ullazine-based supramolecular nanoaggregates in aqueous solution, the formed Frenkel excitons are dissociated to charge-separated excitons by the interlayer charge separation channels, undergoing an ultrafast charge transfer within 0.58 ps and an ultrafast charge separation within 0.67 ps. The Z-schemed charge separation between adjacent layers leads to a significantly enhanced hydrogen yield over U-t-Bu/PVP/Pt, with a hydrogen evolution rate of 369.9 mu molg-1h-1 and an apparent quantum yield of 1.46% at 420 nm. It is 3.8-fold larger than that of ullazine modified with methoxy (U-OMe), without the sigma-pi hyperconjugation.

Abstract :
Liquid metals (LMs) exhibit superior conductivity, flexibility, and malleability, empowering their versatility across multiple fields. It was prevalently believed, albeit lacking in-depth mechanistic insights, that these features stem from high atomic degrees of freedom. In this work, we substantiate the intense and random atomic motion in LMs through the interplay of theory and in situ/operando experiments. In particular, we visualize structural oscillations and crystallographic orientation variations in near-melting LMs; the disordered LM atoms are not confined by rigid crystal lattices, in contrast to their solid counterparts. Owing to the high atomic degrees of freedom, LMs possess adaptive surfaces capable of dynamically conforming to adsorbate configurations during electrocatalysis, especially electrochemical CO2 reduction (CO2R) that has been hindered by the hardship of key species adsorption/activation/desorption on solid-state catalysts. We then pressurize the CO2 to further enhance the adaptability of the LM surface in its interactions with adsorbates. As a result, the reactants and key intermediates are greatly enriched on the liquid metal surface, yielding an even higher CO2R reactivity compared to the ambient-pressure scenario and reaffirming the mechanistic insights.

Abstract :
H2 and O2 evolutions occur simultaneously for conventional particulate photocatalytic overall water splitting (PPOWS), leading to a significant backward reaction and the formation of an explosive H2/O2 gas mixture. This is an issue that must be addressed prior to industrialization of PPOWS. Here, a convenient, cost-effective, and scalable concept is introduced to uncouple hydrogen and oxygen production for PPOWS. Based on this idea, a three-component photocatalyst, Co(5 %)-HPCN/(rGO/Pt), is constructed, consisting of a photoresponsive chip (HPCN), a H2 evolution cocatalyst (rGO/Pt), and a cobalt complex capable of reversibly binding O2 (Co), to achieve the decoupling of PPOWS under alternating UV and visible light irradiations. The asynchronous O2 and H2 evolution strategy have considerable flexibility regarding the photocatalyst structure and light sources suitable for PPOWS.

Abstract :
CH3OH is the most desired product of photocatalytic CH4 conversion. The prominent metal-decorated photocatalyst is challenging in both high yield and selectivity for CH3OH products due to over-oxidation by center dot OH mechanism. Here, interstitial Zn is fabricated into ZniO to induce the formation of Zn atom island for rapid single electron reduction of O2 into center dot OOH instead of center dot OH for the selective combination with methyl into CH3OOH. AuPd alloy is simultaneously decorated on ZniO surface for tuning CH3OOH adsorption and reduction into CH3OH. The synergy of Zn atom island and AuPd alloy achieve a tandem reaction pathway (CH4 -> CH3OOH -> CH3OH) for an unprecedented CH3OH yield of 2444 mmol gAuPd-1 h-1 (or 8800 mu mol gcat-1 h-1) with 98.3% selectivity, which bypasses the center dot OH mechanism for tuning the high selectivity of CH3OH. An apparent quantum efficiency of 18.53% at 370 nm for CH4 conversion are super to the reported photocatalytic systems. Thus, this work provides the new strategy of the synergetic atom island and metal alloy photocatalysts through a tandem reaction pathway to mediate the photocatalytic selective oxidation of CH4 into the desired CH3OH.

Abstract :
Photocatalytic oxidative coupling of amines is considered a mild, efficient, and sustainable strategy for the synthesis of imines. As a versatile organic semiconductor, conjugated microporous polymers (CMPs) are attractive in photocatalysis areas due to the diversity of their polymeric monomers. Herein, we report that in addition to the design of monomers, size-confined polymerization is also a feasible strategy to modulate the structure and photocatalysis properties of CMPs. We adopted dibromopyrazine as polymeric units to prepare pyrazine-involved hollow spherical CMPs (H-PyB) using a template method and successfully performed sizeconfined polymerization of hollow samples by resizing the templates. Interestingly, the small confinement space induced the formation of CMPs with better conjugate extensibility, resulting in enhanced conductivity, narrowed bandgaps, improved photoelectric performance, etc. As a result, small-sized H-PyB CMPs had superior activity for the photocatalytic oxidation of amines. Particularly, the smallest H-PyB CMPs that we designed in the present work exhibited excellent performance for the photocatalytic coupling oxidation of amines. When using benzylamine as a model substrate, the yield of the corresponding imine reached similar to 113 mmol center dot g(- 1)center dot h(-1), accompanied by almost 100 % selectivity. Furthermore, the as-designed confined samples exhibited stable photocatalytic activity as well as good applicability for oxidative coupling of different amines. This work not merely reports a kind of CMP photocatalysts with excellent performance for the imine coupling oxidation but also proposes an alternative strategy for constructing high-performance organic photocatalysts by size-confined synthesis.
