摘　　要：Green hydrogen is the most promising option and a two in one remedy that resolve the problem of both energy crisis and environmental pollution.Wide band gap semiconductors(WBG)(E_(g)>2 eV)are the most prominent and leading catalytic materials in both electro and photocatalytic water splitting(WSR);two sustainable methods of green hydrogen production.WBGs guarantee long life time of photo charge carriers and thereby surface availability of electrons and holes.Therefore,WBG(with appropriate VB-CB potential)along with small band gap materials or sensitizers can yield extraordinary photocatalytic system for hydrogen production under solar light.The factors such as,free energy of hydrogen adsorption(ΔGH^(*))close to zero,high electron mobility,great thermal as well as electro chemical stability and high tunability make WBG an interesting and excellent catalyst in electrolysis too.Taking into account the current relevance and future scope,the present review article comprehends different dimensions of WBG materials as an electro/photo catalyst for hydrogen evolution reaction.Herein WBG semiconductors are presented under various classes;viz.II-VI,III-V,III-VI,lanthanide oxides,transition metal based systems,carbonaceous materials and other systems such as SiC and MXenes.Catalytic properties of WBGs favorable for hydrogen production are then reviewed.A detailed analysis on relationship between band structure and activity(electro,photo and photo-electrochemical WSR)is performed.The challenges involved in these reactions as well as the direction of advancement in WBG based catalysis are also debated.By virtue of this article authors aims to guideline and promote the development of new WBG based electro/photocatalyst for HER and other applications.生产绿氢是应对能源危机和环境污染问题的有效途径,具有广阔的应用前景.宽带隙半导体(WBG,E_(g)>2eV)在电催化和光催化水分解(WSR)反应中表现出卓越的性能,是可持续生产绿氢的关键催化材料.WBG的长寿命光电荷载流子确保了表面有充足的电子和空穴可供利用.因此,具有适当价带-导带(VB-CB)电势的WBG可以与小带隙材料或敏化剂结合,形成在太阳光下高效的光催化制氢体系.WBG具有接近零的氢吸附自由能(△GH^(*))、高电子迁移率、良好的热稳定性和电化学稳定性,以及优异的可调性,因此也成为一种有前景的电解催化剂.本文从不同角度综述了WBG材料在析氢反应(HER)的电/光催化应用.WBG半导体包括II-VI,III-V,III-VI,镧系元素氧化物、过渡金属基体系、碳质材料,以及其他体系,如SiC和MXenes.文章详细归纳了有利于制氢的WBG的催化性能,深入分析了能带结构与活性(包括电催化、光催化和光电化学WSR)之间的关系.同时,展望了生产绿氢反应所面临的挑战以及基于WBG催化的未来研究方向.本文旨在促进用于HER和其他应用的新型WBG基电/光催化剂的开发。
