摘　　要：非晶态催化剂作为一类新型催化材料,具有短程有序长程无序的结构特点,在相同质量下拥有更大的比表面积和结构缺陷,使其在催化反应中具有更多配位不饱和活性位,同时,它不易发生偏析和异相,能保持均匀性和各向同性,可以根据电催化条件自我调节并提供反应所需体积和有效比表面,从而在电解水阴极析氢反应(HER)和阳极析氧反应(OER)中具有优异的催化活性。基于此,结合本课题组在电解水方面的研究工作,综述了近几年非晶态电解水催化剂的最新研究进展,重点介绍了几类非晶态催化剂的可控合成、电催化水分解性能调控策略、表面电子结构与催化活性和稳定性之间的构效关系,并对非晶态的电解水催化剂活性中心的调控面临的挑战和发展进行了展望。Amorphous catalyst as a new type of catalytic material has the characteristics of short-range order and long-range disorder.Compared with the crystalline catalyst,the amorphous catalyst has larger specific surface area and structural defects under the same mass,which makes it more active sites for the catalytic reaction.In addition,the excellent flexibility and flexibility of the amorphous catalyst can induce the active sites to form suitable morphology for promoting the reaction rate due to its uniformity and isotropy,which can adjust their catalytic conditions and provide volume and capacity according to the surface electron transfer,promoting the electrocatalytic activities of hydrogen evolution reaction(HER)and oxygen evolution reaction(OER)in water splitting.Herein,the latest progress in several major types of the amorphous catalysts for electrocatalytic water splitting in recent years was reviewed,especially in the controllable synthesis of several kinds of amorphous catalysts,the control strategy on electrocatalytic performance for water decomposition,and the structure-activity relationship between surface electronic structure and catalytic activity and stability.Moreover,the prospects for the challenges and research direction of the adaptation relationship and modulation of the active site of the catalysts were proposed to shed light on further development of electrolysis water.
