摘　　要：电解水是一种较有前景的氢能制取方法,但Ir和Pt等贵金属催化剂限制了其大规模商业化推广应用,为了进一步降低电解水制氢的成本,开发高效稳定和低成本的电催化剂是当前研究的重点。通过理论计算方法找到催化剂结构、中间体吸附特性与催化活性之间的一般规律有助于催化剂的理性设计,降低新型催化剂的研发成本。“火山型”关系被广泛应用于电解水的析氢反应(HER)和析氧反应(OER)中,为高通量筛选高活性催化剂提供基础理论。总结了HER和OER的反应机理,阐述了HER和OER中火山型关系的基本概念,综述了构建火山型关系的一般方法。Water-electrolysis is a promising technology for hydrogen production, but the precious metal catalysts(such as Ir and Pt) used in water-electrolysis limit its commercial application at a large scale. In order to further reduce the cost of hydrogen production by water-electrolysis, the development of efficient, stable and low-cost electrocatalysts is the focus of current research. Theoretical calculation is helpful to find out the general principle between catalysts structure, adsorption properties of intermediates and catalytic activity to reduce the research and development cost of novel catalysts. The volcano relationships are widely used in hydrogen evolution reaction(HER) and oxygen evolution reaction(OER) to provide a fundamental theory for high-throughput screening of high-active catalysts. The reaction mechanism of HER and OER is summarized, the basic concept of the volcano relationships of HER and OER is expounded, and the general method constructing the volcano relationships is also summarized.
