Abstract ：
Presented herein are the delicate design and synthesis of S-scheme NiTiO3 /CdS heterostructures composed of CdS nanoparticles anchored on the surface of NiTiO3 nanorods for photocatalytic CO2 reduction. Systematic physicochemical studies demonstrate that NiTiO3 /CdS hybrid empowers superior light absorption and enhanced CO2 capture and activation. Electron spin resonance validates that the charge carriers in NiTiO3 /CdS follow a S-scheme transfer pathway, which powerfully impedes their recombination and promotes their separation. Importantly, the photogenerated holes on CdS are effectively consumed at the hero-interface by the electron from NiTiO3 , preventing the photo-corrosion of the metal sulfide. As a result, with Co(bpy)3 2 + as a cocatalyst, NiTiO3 /CdS displays a considerable performance for CO2 reduction, affording a high CO yield rate of 20.8 mu mol h-1 . Moreover, the photocatalyst also manifests substantial stability and good reusability for repeated CO2 reaction cycles in the created tandem photochemical system. In addition, the possible CO2 photoreduction mechanism is constructed on the basis of the intermediates monitored by in-situ diffuse reflectance infrared Fourier transform spectroscopy.

Abstract ：
The efficiency of photocatalytic hydrogen evolution is fundamentally constrained by limited charge carrier separation. Herein, we deliberately engineered an electric double layer (EDL) via surface modification with positively charged molecules, which optimizes the charge carrier dynamics. The anchoring of both diethylenetriamine (DETA) molecules and Pt species on CdS (denoted as Pt/CdS-D) achieves remarkable H2 evolution performance, delivering an exceptional rate of 6295 mu mol g-1 h-1 and an apparent quantum efficiency of 14.9%, which is 26.7-fold enhanced compared to that of CdS. The synergistic modification strategy concurrently lowers the activation energy barrier for water reduction and establishes EDL-driven directional charge transport channels that boost carrier separation efficiency. This work provides a paradigm for designing high-performance photocatalysts through the rational integration of functional organic groups and cocatalysts, opening new avenues for advanced solar-to-hydrogen energy conversion systems.

Abstract ：
Photocatalytic CO2 conversion with H2O to carbonaceous fuels is a desirable strategy for CO2 management and solar utilization, yet its efficiency remains suboptimal. Herein, efficient and durable CO2 photoreduction is realized over a Ru-NPs/Ru-PHI catalyst assembled by anchoring Ru single atoms (SAs) and nanoparticles (NPs) onto poly(heptazine imide) (PHI) via the in-plane Ru-N-4 coordination and interfacial Ru-N bonds, respectively. This catalyst shows an unsurpassed CO production (32.8 mu mol h(-1)), a record-high apparent quantum efficiency (0.26%) beyond 800 nm, and the formation of the valuable H2O2. Ru SAs tune PHI's electronic structure to promote in-plane charge transfer to Ru NPs, forming a built-in electron field at the interface, which directs electron-hole separation and rushes excited electron movement from Ru-PHI to Ru NPs. Simultaneously, Ru SAs introduce an impurity level in PHI to endow long-wavelength photoabsorption, while Ru NPs strengthen CO2 adsorption/activation and expedite CO desorption. These effects of Ru species together effectively ensure CO2-to-CO conversion. The CO2 reduction on the catalyst is revealed to follow the pathway CO2 -> *CO2 -> *COOH -> *CO -> CO, based on the intermediates identified by in situ diffuse reflectance infrared Fourier transform spectroscopy and further supported by density functional theory calculations.

Abstract ：
As a crystalline allotrope of carbon nitrides, poly (heptazine imide) (PHI) exhibits great potential for photocatalytic reforming of biomass-derived alcohols. However, its activity is greatly constrained due to insufficient charge migration and severe non-radiative recombination. To address this issue, PHI with high interlayer stacking orderliness is fabricated through a facile ion exchange strategy. Characterizations reveal that rational modification of the interlayer stacking mode of PHI could efficiently suppress non-radiative recombination and improve charge transfer efficiency. Accordingly, the optimal sample exhibits high photocatalytic reforming activity for H2 evolution, which is up to 2.16 mmolg-1h-1, and with a quantum efficiency reaches 26.7% at 400 nm.

Abstract ：
Lattice oxygen (LO)-mediated photothermal dry reforming of methane (DRM) presents a promising approach to syngas production. However, realizing high DRM efficiency and durability remains challenging due to the difficulty in activating LOs in catalysts. Herein, we demonstrate that partially substituting Fe sites in perovskite ferrite (LaFeO3) by Mn triggers LOs, bestowing the catalyst with superior activity and stability for photothermal DRM after modification with Ru. The Mn exchange induces a charge transfer from La to Mn, which combined with the incoming photoexcited electrons reconstructs the perovskite's electronic structure, weakening the La-O-Mn bonds and facilitating the LO migration. Meanwhile, photogenerated holes migrate to surface LOs, further enhancing their reactivity to mediate DRM. Under light irradiation, the catalyst exhibits an outstanding syngas production rate (H2: 42.89 mol gRu -1 h-1, CO: 54.92 mol gRu -1 h-1) while stably operating over 150 h. It also achieves a methane turnover frequency of 0.9 s-1 and a light-to-chemical energy efficiency of 15.3%, setting a benchmark for light-driven DRM performance. This work underscores the significance of exact site doping in metal oxides to fine-tune LO activity, providing valuable guidance for fabricating efficient catalysts for solar-powered redox reactions proceeded via the light-supported Mars-van Krevelen mechanism.

Abstract ：
Polymeric carbon nitrides (PCNs), usually the melon phase, have been extensively applied as photocatalysts for CO2 reduction; however, their performance is still unsatisfactory. The condensed allotrope, namely, poly(triazine imide) (PTI) with extended conjugation and a crystallized structure, indeed holds more favorable compositional and structural advantages for photocatalytic CO(2)reduction but remains to be fully exploited. Herein, hexagonal prism-shaped PTI crystals were synthesized and developed as a high-performance photocatalyst for CO2 reduction. With Co(bpy)(3) (2+) as a cocatalyst, the PTI crystals exhibit a CO evolution rate of 44 mu mol h(-1) (i.e., 1467 mu mol g(-1) h(-1)) with 93% selectivity, markedly superior to that of the melon counterpart. Moreover, PTI crystals manifest an apparent quantum efficiency of 12.9% at 365 nm, representing the state-of-the-art value by PCN photocatalysts for CO2-to-CO reduction without using noble metals. The surface pyridine N species of PTI are exposed as active sites to dominate CO2 activation and conversion, which, together with the high crystallinity to facilitate charge separation and transport, endows high CO2 reduction efficiency. In situ diffuse reflectance infrared Fourier transform spectroscopy determines the key intermediates during the CO2 reduction reaction and, consequently, constructs the possible reaction mechanism.

Abstract ：
Elevating the long-wavelength activation of photocatalysts represents a formidable approach to optimizing sunlight utilization. Polythiophene (PTh), although renowned for its robust light absorption and excellent conductivity, is largely overlooked for its potential as a photocatalyst due to the swift recombination of photogenerated charge carriers. Herein, we unveil that the strategic introduction of an aromatic ring containing varying nitrogen content into PTh instigates polarized charge distribution and facilitates the narrowing of the band gap, thereby achieving efficient photocatalytic activities for both hydrogen and hydrogen peroxide generation. Notably, the best sample, PTh-N2, even demonstrates photocatalytic activity in the red light region (600-700 nm). This study offers a promising avenue for the development of polymer photocatalysts with efficient photocatalytic performance for red light-induced photocatalysis.

Abstract ：
Among the current industrial hydrogen production technologies, electrolysis has attracted widespread attention due to its zero carbon emissions and sustainability. However, the existence of overpotential caused by reaction activation, mass/charge transfer, etc. makes the actual water splitting voltage higher than the theoretical value, severely limiting the industrial application of this technology. Therefore, it is particularly important to design and develop highly efficient electrocatalysts to reduce overpotential and improve energy efficiency. Among the various synthesis methods of electrocatalysts, electrochemical synthesis stands out due to its simplicity, easy reaction control, and low cost. This review article classifies and summarizes the electrochemical synthesis techniques (including electrodeposition, electrophoretic deposition, electrospinning, anodic oxidation, electrochemical intercalation, and electrochemical reconstruction), followed by their application in the field of water electrolysis. In addition, some challenges currently faced by electrochemical synthesis in electrocatalytic hydrogen production, and their potential solutions are discussed to promote the practical application of electrochemical synthesis in water electrolysis.Graphical AbstractThis review summarizes and classifies commonly used electrochemical synthesis techniques, followed by the application of electrochemical synthesis methods in research on water electrolysis. Additionally, some challenges faced by electrochemical synthesis in the field of water electrolysis and possible solutions are discussed.

Abstract ：
Photocatalytic CO2 reduction (PCR) is limited by unsatisfied activity and selectivity. The integration of molecular photocatalysts with semiconductors can solve the above two issues simultaneously. However, most of the organic-inorganic heterojunctions are bulky-based morphologies, which are still restricted by the control of surface areas and charge transfer. Herein, a tandem dual Z-scheme heterostructure was synthesized by assembling cobalt porphyrin ([meso-tetra (4-sulfonate phenyl) porphyrinato], CoTPPS) on hollow-structured TiO2@ZnIn2S4 (H-TiO2@ZIS). The optimized H-TiO2@ZIS@CoTPPS exhibits superior solar fuel evolution of 158.15 mu molCO g-1 center dot h-1 via the PCR process, which is superior to most reported TiO2 and ZIS-based photo-catalysts. The exceptional photocatalytic performance is ascribed to enhanced light absorption, elevated surface areas, directed charge separation, and improved CO2 activation. Specifically, the double built-in electric field (IEF) and the Zn-O bond of dual Z-scheme structures facilitate fast charge separation. Detailed charge transfer dynamics of H-TiO2@ZIS@CoTPPS are investigated by experimental characterizations and density functional theory (DFT) calculations. This investigation provides atomistic insight into unique dual Z-scheme heterostructure and offers a new paradigm for solar-driven energy conversion

Abstract ：
Carbon - based single - atom catalysts, a promising candidate in electrocatalysis, offer insights into electron- donating effects of metal center on adjacent atoms. Herein, we present a practical strategy to rationally design a model catalyst with a single zinc (Zn) atom coordinated with nitrogen and sulfur atoms in a multilevel carbon matrix. The Zn site exhibits an atomic interface configuration of ZnN4S1, where Zn's electron injection effect enables thermal- neutral hydrogen adsorption on neighboring atoms, pushing the activity boundaries of carbon electrocatalysts toward electrochemical hydrogen evolution to an unprecedented level. Experimental and theoretical analyses confirm the low- barrier Volmer-Tafel mechanism of proton reduction, while the multishell hollow structures facilitate the hydrogen evolution even at high current intensities. This work provides insights for understanding the actual active species during hydrogen evolution reaction and paves the way for designing high- performance electrocatalysts.
