摘要 电解水制氢是当前实现太阳能和风能等间歇式可再生能源高效利用的一种绿色能源储存和转化技术;生物质炭材料继承了生物质的天然三维空间结构特性,具有高机械稳定性的多孔自支撑构型,因而在构筑低成本、高比表面积和物化性质增强的催化剂方面展现出非常有潜力的应用前景;主要介绍了自支撑型生物质炭基电解水析氧催化剂的制备方法,以及在催化电解水析氧反应(oxygen evolution reaction,OER)中的最新进展,并对该领域面临的机遇和挑战进行了展望。 Hydrogen production from water electrolysis is considered as a green energy storage and conversion technology to realize the efficient utilization of intermittent renewable energy including solar energy and wind energy.Biochar inheriting the natural three-dimensional structure nature of biomass could obtain porous self-supporting structure with the high mechanical stability easily,thus exhibiting a great potential in the construction of catalysts with low cost,high specific surface area and enhanced physicochemical properties.In this review,we mainly focus on the synthesis strategies of free-standing biochar-based catalysts for oxygen evolution of water electrolysis and the latest progress in the application of electrocatalyzing oxygen evolution reaction(OER)of water splitting.Furthermore,the opportunities and challenges in this field are prospected.
