| 摘 要： | 高效、清洁的氢能被认为是化石能源最有潜力的替代能源之一。制氢方法中电解水制氢是非常简便、且易于规模化的一种方法,但是电解水过程中存在制氢能耗增加、成本升高等问题,因此制备能耗低、具有稳定催化效率的催化剂成为能源领域的研究热点。层状双金属氢氧化物（LDHs）由于具有独特的二维层状结构,使其组成易于调节、结构易于调控,因此具有高效的电催化活性。但是,LDHs存在尺寸大、厚度高的问题,导致电催化剂的活性位点的数目受限、本征活性低和电导率低,最终会影响LDHs的电催化性能。主要论述了LDHs的结构和电解机理以及作为电解水催化剂的研究现状,对目前存在的问题以及解决方法进行了归纳,并对未来的研究方向进行了展望。

| Abstract: | High-efficiency and clean hydrogen energy is considered to be one of the most potential alternative energy sources for fossil energy.In the hydrogen production method,the electrolysis of water to produce hydrogen is a very simple and easy to scale method,but there is an increase in the energy consumption and cost of hydrogen production in the process of electrolysis of water.Therefore,the preparation of catalyst with low energy consumption and stable catalytic efficiency has become a hotspotsin the research field of energy source.Layered double hydroxides（LDHs） have unique two-dimensional layered struc-ture,which makes their composition and structure easy to be controlled,so they have high-efficiency electrocatalytic activity.However,LDHs have the problems of large size and high thickness,which result in limited number of active sites of electro-catalysts,low intrinsic activity and low conductivity,which will eventually affect the electrocatalytic performance of LDHs.The structure and electrolysis mechanism of LDHs,as the current research status of water electrolysis catalysts was mainly discussed in this article.The current problem and solution were summarized and the future research direction was prospected. |
