Abstract ：
The oxidative dehydrogenation of propane (ODHP) represents a highly promising route for the industrial-scale production of propene. Non-metallic boron nitride (BN)-based materials, known for their high propene selectivity, have emerged as next-generation ODH catalysts. However, the real active sites on surfaces remain unclear due to the absence of visual experimental evidence. In this work, we introduce a chemical titration approach to clarify the active centers of NaOH modified BN (BN-NaOH) catalysts for ODHP. The BN-NaOH catalyst demonstrates outstanding performance, achieving over 90 % olefin selectivity and a stable propane conversion of 23.2 %. Notably, the turnover frequency (TOF) for B-OH sites reaching 1.2 h- 1, which significantly surpassed that of unmodified BN catalysts (0.6 h- 1). In situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) analysis revealed that the formation of OH-nests on the BN-NaOH surface was primarily accountable for the enhanced reactivity. Moreover, the crucial role of these OH-nests during ODHP was further validated through selective chemical titration of B-OH groups using benzoic anhydride.

Abstract ：
Harnessing supramolecular interactions to regulate the structure and performance of functional materials is a key challenge in materials chemistry. Herein, the study utilizes 18-crown-6 (18C6) ether-assisted alkali-metal (Na, K, Cs) copper(I) iodide supramolecular assemblies to precisely regulate the material structures. This approach facilitated the transition from 1D mono-royal crown coordination (18C6@KCuI2, CKCI) to 0D di-royal crown ((18C6)(2)@Na-2(H2O)(3)Cu4I6, CNCI) and tri-royal crown ((18C6)(3)@Cs2Cu2I4, CCCI) structures. Interestingly, the CCCI single-crystal exhibits outstanding scintillation properties, with a high relative light yield of 71 000 photons MeV-1 and an ultralow detection limit of 39.3 nGy s(-1), which can be attributed to the synergistic effects of 18C6 and copper-iodide clusters. It stabilizes the self-trapped exciton state, enhances exciton localization, and reduces non-radiative losses, thus resulting in a large Stokes shift of 193 nm and near-unity photoluminescence quantum yield of 99.4%. Additionally, 18C6 can promote crystal nucleation and growth, making it easy to prepare centimeter-scale transparent single crystals with >80% transmittance, such as CCCI single crystal can achieve an ultrahigh-resolution X-ray imaging of 26.3 lp mm(-1). It demonstrates that the structure and performance of halide scintillators can be regulated through supramolecular interactions, which provides a new approach for developing high-performance scintillator materials.

Abstract ：
Iron-nitrogen-carbon (Fe-N-C) catalyst has emerged as highly promising contender for oxygen reduction reaction (ORR), yet challenges such as limited active site accessibility and intricate synthesis procedures impede their commercialization as a replacement for the benchmark Pt/C catalyst. Herein, we present an innovative approach to in situ fabricate a unique iron and nitrogen co-doped 3D porous carbon material. The material is synthesized through a straightforward one-step pyrolysis of xanthine, oxidized carbon nanotubes and iron nitrate nonahydrate mixture. During the high temperature pyrolysis, the nucleobase xanthine undergoes gradually transformation into an efficient N-doped graphene-like material. Simultaneously, it assembles with carbon nanotubes (CNTs), resulting in the formation of a unique 3D graphene-CNTs composite structure composed of graphene and CNTs. This exceptional 3D porous structure serves as an excellent scaffold, ensuring firm anchoring, uniform dispersion, and optimal exposure of numerous FeNx active sites. Leveraging this well-engineered framework, the optimized Fe-N-C catalyst (NC/CNT/Fe0.04) shows excellent ORR performance with an onset potential of 1.03 V vs. RHE, a half-wave potential of 0.87 V vs. RHE, and a diffusion-limited current density of −5.59 mA cm−2, even better than those of the commercial Pt/C catalyst.

Abstract ：
Developing novel electrocatalysts for achieving high selectivity and faradaic efficiency in the carbon dioxide reduction reaction (CO2RR) poses a major challenge. In this study, a catalyst featuring a nitrogen-doped carbon shell-coated Ni nanoparticle structure is designed for efficient carbon dioxide (CO2) electroreduction to carbon monoxide (CO). The optimal Ni@NC-1000 catalyst exhibits remarkable CO faradaic efficiency (FECO) values exceeding 90% across a broad potential range of -0.55 to -0.9 V (vs. RHE), and attains the maximum FECO of 95.6% at -0.75 V (vs. RHE) in 0.5 M NaHCO3. This catalyst exhibits sustained carbon dioxide electroreduction activity with negligible decay after continuous electrolysis for 20 h. More encouragingly, a substantial current density of 200.3 mA cm(-2) is achieved in a flow cell at -0.9 V (vs. RHE), reaching an industrial-level current density. In situ Fourier transform infrared spectroscopy and theoretical calculations demonstrate that its excellent catalytic performance is attributed to highly active pyrrolic nitrogen sites, promoting CO2 activation and significantly reducing the energy barrier for generating *COOH. To a considerable extent, this work presents an effective strategy for developing high-efficiency catalysts for electrochemical CO2 reduction across a wide potential window.

Abstract ：
Non-metallic heteroatom-doped carbon materials are promising catalysts for the oxidative dehydrogenation of propane (ODHP), but their controlled synthesis remains challenging. Herein, a novel three-dimensional N, P co-doped carbon nanosheet (NPC-NS-T) catalyst is prepared, which shows an impressive catalytic performance in the ODHP reaction with high propane conversion (20.0%) and high selectivity for propene (62.1%) and olefins (64.5%) at 500 degrees C along with good long-time stability. Comprehensive experimental characterizations revealed that incorporation of appropriate P can not only help to form more C 00000000 00000000 00000000 00000000 11111111 00000000 11111111 00000000 00000000 00000000 O species on the surface of NPC-NS-T but also inhibit the consumption of CO species under ODHP conditions, thereby remarkably improving the catalytic performance.

Abstract ：
Biomolecule self-assembly shows great potential in the preparation of ordered functional materials. Here, we prepare a gauzy NC material via water guiding guanine biomolecule self-assemble, which exhibits the better ethylbenzene conversion (similar to 50%), styrene selectivity (similar to 91%) and long-term stability (>40 h) in ODH of ethylbenzene to styrene than that of guanine solid self-assembly produced NC (38% conversion vs. 88% selectivity) sample. The study shows that water not only facilitates guanine biomolecule self-assembly to form more stable octamer structure but restrains vertical growth of guanine, and resultant NC-1000-12 h holds high density active sites and outstanding oxidation resistance, thus enhancing NC catalytic performance. Overall, current work provides a new understanding on preparation of highly efficient NC materials through supramolecular self-assembly strategy.

Abstract ：
Maximization the synergistic effect of each component in transition metal-carbon complexes is expected to improve the bifunctional oxygen electrocatalysis for rechargeable Zn-air batteries but is still challenging. Herein, nucleobase guanine is employed as a supramolecular precursor to generate the core (FeCo alloy)-shell (carbon) structure embedded in ultrathin graphene-like nitrogen-doped carbon nanosheets (FeCo@NCNSs) via a confinement pyrolysis strategy. Thanks to the generated core-shell structure and bimetallic synergistic effect, the as-prepared FeCo@NCNSs exhibits excellent electrochemical performance in both oxygen reduction reaction and oxygen evolution reaction. As a result, when served as the bifunctional air electrode for a practical Zn-air battery, FeCo@NCNSs exhibits a higher open-circuit voltage (1.553 V) and peak power density (197.30 mW cm-2), as well as the greatly improved long-term cyclic stability compared to the noble metal benchmarks. This work provides a promising approach to integrate various active sites for bifunctional oxygen electrocatalysis and inspires the exploration of simple but efficient electrocatalysts for energy storage and conversion.

Abstract ：
5-Hydroxymethylfurfural (HMF) is a widely used biomass platform chemical that plays a crucial role in bridging biomass and fossil resources. Electrocatalytic oxidation of HMF provides an efficient way to obtain high-value-added biomass-derived chemicals, among which the intermediate product 5-formyl-2-furan carboxylic acid (FFCA) has attracted considerable attention. However, the weak adsorption ability of monometallic nickel oxide (NiOx) to HMF in neutral electrolyte restricts its further development, resulting in low HMF conversion and FFCA yield. In this study, we successfully constructed a novel nickel oxide-platinum oxide hybrid catalyst supported on carbon felt (NiOx-PtOx/CF), which exhibits an optimized adsorption ability of HMF, leading to the outstanding FFCA yield up to 77 % in the neutral media. The high activity of the NiOx-PtOx/CF catalyst can be attributed to the redistribution of the electrons and the optimization of the electronic structure on the Ni active site due to the introduction of PtOx on NiOx nanosheets. This study offers valuable insights for the design of efficient multicomponent electrocatalysts for electrocatalytic biomass refinery systems. Highly efficient of HMF into FFCA on a NiOx-PtOx/carbon felt composite electrode is achieved at a potential of 1.78 VRHE with high value product of FFCA yield up to 77 %. The high activity of the NiOx-PtOx/CF catalyst can be attributed to the redistribution of the electrons and the optimization of the electronic structure on the Ni active site due to the introduction of PtOx on NiOx nanosheets. image

Abstract ：
Iron and nitrogen co-doped carbon-based catalysts have garnered significant attention for their efficacy in the degradation of Rhodamine B (RhB), Tetracycline (TC) and other organic pollutants through peroxymonosulfate (PMS) activation. However, designing catalysts with both high activity and abundant active sites has proven challenging, primarily due to the limited understanding of the structure-activity relationship. Herein, we present a straightforward synthesis of iron and nitrogen co-doped carbon nanosheets (FeNC) that exhibit exceptional activity in activating PMS for degradation of RhB and TC. The FeNC material shows robust resistance to interference across a wide pH of 1.5 to 10, resistance to inorganic anions and humic acid (HA). More importantly, the Fe3C nanoparticles are uniformly anchored within the carbon layer, effectively prevent metal leaching. Unlike the traditional sulfate radical-based advanced oxidation processes, our study reveals that non -radical singlet oxygen (1O2) serves as the main reactive oxygen species (ROS) responsible for the degradation processes through quenching tests and electron paramagnetic resonance (EPR) analysis. Structural characterizations and spectroscopic study indicate that the potential active sites on FeNC, namely C--O, graphitic and pyridinic nitrogen play an important role in this degradation. Particularly noteworthy is the discovery that Fe3C species, present in the FeNC-900/PMS system, also contribute significantly to the degradation of TC. Moreover, we have proposed potential degradation pathways for RhB and TC based on the results of liquid chromatograph mass spectrometer (LC -MS) measurement. Overall, this study offers novel insights into the development of heterogeneous iron and nitrogen co-doped carbon-based catalysts for advanced oxidation processes (AOPs) via PMS activation.
