摘要
电解水制氢是实现我国"双碳"目标的重要技术之一,其实际应用需要开发低成本、高活性和高稳定性的催化剂.近年来,双原子催化剂在电解水制氢领域受到了广泛的关注.本文在对前驱体预选法、热迁移法、双溶剂法、自组装和原子层沉积等几种常用的双原子催化剂合成方法进行综述的基础上,进一步总结了双原子催化剂在电解水制氢中的应用情况,指出双原子催化剂的应用仍停留在实验室阶段,尚未达到工业化标准,强调为实现其在HER领域的实际应用,应加强双原子催化剂合成方法的精确性、非贵金属双原子催化剂的合成以及双原子催化剂的反应机制等方面的研究.
Abstract
Hydrogen production from water electrolysis is a key technology to achieving China's car-bon peaking and carbon neutrality goal,and its practical application requires the development of low-cost,high-activity and high-stability catalysts.In recent years,DACs have received extensive attention in the field of hydrogen production through water electrolysis.This review discusses several common synthesis methods for DACs,including precursors preselection,thermal migration,double solvents,self-assembly,and atomic layer deposition.Furthermore,it summarizes the application of DACs in electrolytic water split-ting.The application is still at the laboratory stage and has not yet reached industrial standards.To achieve practical application in HER,it is essential to enhance research on the precision of synthesis methods,the stability of catalysts,the synthesis of non-noble metal dual-atom catalysts,and the reaction mechanism of DACs.
