In recent years, hydrogen energy has emerged on the stage of history as the most promising clean energy carrier of the 21st century. Among the current methods of producing hydrogen, photocatalytic hydrogen production technology, as a zero-carbon approach to producing high calorific value and pollution-free hydrogen energy, has attracted much attention since its discovery. As the core of photocatalysis technology, semiconductor photocatalysts are always the research hotspots. Among them, graphite-phase carbon nitride (g-C₃N₄), an organic semiconductor material composed of only C and N elements, possesses physicochemical properties incomparable to those of traditional inorganic semiconductor materials, including suitable energy band positions, easy structural regulation, inexpensive raw materials and abundant reserves, simple preparation, high thermal/mechanical/chemical stability, etc. Therefore, g-C₃N₄ has attracted extensive attention in the field of photocatalytic hydrogen production in the last two decades. This review comprehensively outlines the research trajectory of g-C₃N₄ photocatalytic hydrogen production, encompassing development, preparation methods, advantages, and disadvantages. A concise introduction to g-C₃N₄ is provided, as well as an analysis of the underlying mechanism of the photocatalytic system. Additionally, it delves into the latest techniques to enhance performance, including nanostructure design, elemental doping, and heterojunction construction. The applications of g-C₃N₄ based photocatalysts in hydrogen production are surveyed, underscoring the significance of catalyst active sites and g-C₃N₄ synthesis pathways. At length, concluded are insights into the challenges and opportunities presented by g-C₃N₄ based photocatalysts for achieving heightened hydrogen production.</p></div>","PeriodicalId":61638,"journal":{"name":"材料导报:能源(英文)","volume":"3 4","pages":"Article 100235"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666935823000952/pdfft?md5=89df3bbb28585918e4017393280c5cac&pid=1-s2.0-S2666935823000952-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136159629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, various interface regulation strategies have been adopted to optimize the BiVO₄ photoanode. This review provides an in-depth analysis for the mechanism of interface regulation strategies from the perspective of factors affecting the PEC performance of BiVO₄ photoanodes. These interface regulation strategies improve the PEC performance of BiVO₄ photoanode by promoting charge separation and transfer, accelerating interfacial reaction kinetics, and enhancing stability.

Herein, a facile synthesis of anatase TiO₂ nanosheets with an abundance of surface oxygen vacancies (TiO₂-OV) via the calcination treatment was reported. Photocatalytic experiments of the prepared anatase TiO₂ samples showed that TiO₂-OV nanosheets exhibited remarkably increased ammonia yield for solar-driven N₂ fixation in pure water, without adding any sacrificial agents. EPR, XPS, XRD, UV-Vis DRS, TEM, Raman, and PL techniques were employed to systematically explore the possible enhanced mechanism. Studies revealed that the introduced surface oxygen vacancies significantly extended the light absorption capability in the visible region, decreased the adsorption and activation barriers of inert N₂, and improved the separation and transfer efficiency of the photogenerated electron-hole pairs.

Herein, we developed two metal-organic Cu-MOF and Bi-MOF layers using benzene tricarboxylic acid (H₃BTC) ligands on CuBi₂O₄ photocathodes. Both MOF layers drastically improved the photoelectrochemical stability by suppressing the photo-corrosion through conformal surface passivation. The Cu-MOF modified CuBi₂O₄ showed more significant charge separation and transfer efficiencies than the Bi-MOF modified control. Based on the transient photocurrent curves under the applied potential of 0.6 V vs. RHE, the rate-law analysis showed the CO₂ photoreduction took place through a first-order reaction. Further, the photoelectrochemical impedance spectra (PEIS) revealed this reaction order, representing an “operando” analysis. Moreover, the reaction rate constant on Cu-MOF modified sample was higher than that on Bi-MOF modified one and bare CuBi₂O₄.
