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 ：
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 ：
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 ：
The photocatalytic selective oxidation of CH4 to value-added higher hydrocarbons presents a promising avenue for the sustainable development of the chemical industry; however, the mild activation and conversion of CH4 remain great challenges. Herein, a novel Au/Zn2Ti3O8 hybrid photocatalyst is assembled from supporting Au nanoparticles (NPs) on the surface of Zn2Ti3O8 nanospheres. The Zn2Ti3O8 semiconductor with Zn2+ active sites drives the CH4 coupling reaction, while the Au NPs promote the separation and migration of charge carriers. When irradiated with a 365 LED light, the 1.0%-Au/Zn2Ti3O8 catalyst exhibits high activity and stability for selective CH4 coupling with O-2, affording an optimal C2H6 yield of 609.49 mu mol g(-1) h(-1) with 80.18% selectivity, which is among the state-of-the-art values under comparable conditions. Besides, the 1.0%-Au/Zn2Ti3O8 sample affords a turnover number (TON) of 239.1 and an apparent quantum efficiency (AQE) of 1.05% at 365 nm. Studies reveal that the Schottky junction interface strongly promotes photoinduced electrons to be transferred to Au from Zn2Ti3O8, realizing directed separation and migration of charge carriers for high photocatalytic activity. Various in situ spectroscopy analyses expose that the key (CH3)-C-center dot species in CH4-to-C2H6 conversion are stabilized by the surface Au sites for the subsequent coupling reaction to form C2H6, which prevents the undesirable overoxidation reaction to afford high C2H6 selectivity. A possible photocatalytic oxidative CH4 coupling mechanism over the Au/Zn2Ti3O8 hybrid is also proposed.

Abstract ：
Thermal catalytic oxidative dehydrogenation of ethane with O2 has been extensively studied as an approach for ethene production, but this approach is energy intensive and has disadvantages of overoxidation, high-cost and safety concerns. Herein, we present ZnO-supported Pt nanoparticles that are highly active and selective for dehydrogenating ethane to ethene with simulated sunlight via a photo-supported Mars-van Krevelen mechanism. The Pt/ZnO catalyst achieves a high ethane-to-ethene conversion rate of 867.8 mu mol h-1 g-1 and an excellent selectivity of 97.56%. Besides, it is also coking-resistant and can be readily revived by exposure to O2 for refilling the consumed lattice oxygen to preserve its original activity. It is revealed that the Pt species facilitate C2H4 desorption from the catalyst to inhibit overoxidation and enhance separation of light-induced charges to boost the photocatalytic efficiency. Whilst the photogenerated holes on ZnO are captured by surface lattice oxygen to generate active O- species, H atoms were extracted from adsorbed C2H6 to produce C2H4. In situ diffuse reflectance infrared Fourier transform spectroscopy is applied to detect the key intermediates and thus propose the possible catalytic EDH process over the Pt/ZnO photocatalyst. A Pt/ZnO photocatalyst is efficient and reusable for ethene production from ethane dehydrogenation with simulated sunlight, affording outstanding C2H4 productivity of 867.8 mu mol h-1 g-1 and selectivity of 97.56%.

Abstract ：
Thermocatalytic nonoxidative ethane dehydrogenation(EDH)is a promising strategy for ethene produc-tion but suffers from intense energy consumption and poor catalyst durability;exploring technology that permits efficient EDH by solar energy remains a giant challenge.Herein,we present that an oxygen va-cancy(Ov)-rich LaVO4(LaV04-Ov)catalyst is highly active and stable for photocatalytic EDH,through a dynamic lattice oxygen(Olatt.)and Ov co-mediated mechanism.Irradiated by simulated sunlight at mild conditions,LaVO4-Ov effectively dehydrogenates undiluted ethane to produce C2H4 and CO with a con-version of 2.3％.By loading a small amount of Pt cocatalyst,the evolution and selectivity of C2H4 are en-hanced to 275 μmol h-1 g-1 and 96.8％.Of note,LaVO4-Ov appears nearly no carbon deposition after the reaction.The isotope tracked reactions reveal that the consumed Olatt.recuperates by exposing the used catalyst with O2,thus establishing a dynamic cycle of Olatt,and achieving a facile catalyst regeneration to preserve its intrinsic activity.The refreshed LaVO4-Ov exhibits superior reusability and delivers a turnover number of about 305.The Ov promotes photo absorption,boosts ethane adsorption/activation,and accel-erates charge separation/transfer,thus improving the photocatalytic efficiency.The possible photocatalytic EDH mechanism is proposed,considering the key intermediates predicted by density functional theory(DFT)and monitored by in-situ diffuse reflectance infrared Fourier transform spectroscopy(DRIFTS).

Abstract ：
Electrochemical reduction reactions, as cathodic processes in many energy-related devices, significantly impact the overall efficiency determined mainly by the performance of electrocatalysts. Metal-organic frameworks (MOFs) derived carbon-supported metal materials have become one of star electrocatalysts due to their tunable structure and composition through ligand design and metal screening. However, for different electroreduction reactions, the required active metal species vary in phase component, electronic state, and catalytic center configuration, hence requiring effective customization. From this perspective, this review comprehensively analyzes the structural design principles, metal loading strategies, practical electroreduction performance, and complex catalytic mechanisms, thereby providing insights and guidance for the future rational design of such electroreduction catalysts. Recent advances on the different electroreduction applications of metal-organic framework derived carbon-supported metal electrocatalysts with customized structure, component, and electron structure are depicted. Thereout, morphology control, component/construction modulation and controlled metal loading strategies are systematically sorted out based on three key components of metal-organic frameworks, namely metal nodes, ligands and modifiers. image

Abstract ：
The selective conversion of ethane (C2H6) to ethylene (C2H4) under mild conditions is highly wanted, yet very challenging. Herein, it is demonstrated that a Pt/WO3-x catalyst, constructed by supporting ultrafine Pt nanoparticles on the surface of oxygen-deficient tungsten oxide (WO3-x) nanoplates, is efficient and reusable for photocatalytic C2H6 dehydrogenation to produce C2H4 with high selectivity. Specifically, under pure light irradiation, the optimized Pt/WO3-x photocatalyst exhibits C2H4 and H2 yield rates of 291.8 and 373.4 mu mol g-1 h-1, respectively, coupled with a small formation of CO (85.2 mu mol g-1 h-1) and CH4 (19.0 mu mol g-1 h-1), corresponding to a high C2H4 selectivity of 84.9%. Experimental and theoretical studies reveal that the vacancy-rich WO3-x catalyst enables broad optical harvesting to generate charge carriers by light for working the redox reactions. Meanwhile, the Pt cocatalyst reinforces adsorption of C2H6, desorption of key reaction species, and separation and migration of light-induced charges to promote the dehydrogenation reaction with high productivity and selectivity. In situ diffuse reflectance infrared Fourier transform spectroscopy and density functional theory calculation expose the key intermediates formed on the Pt/WO3-x catalyst during the reaction, which permits the construction of the possible C2H6 dehydrogenation mechanism. The Pt/WO3-x photocatalyst consisted of ultrafine Pt nanoparticles supported on the surface of oxygen-defective tungsten oxide nanoplates manifests high activity and fine reusability for selective ethylene formation from ethane dehydrogenation by simulated sunlight under mild conditions. image
