在污染日趋严重的今天,环境催化技术愈发重要。催化剂催化性能与其活性位点息息相关,传统纳米催化剂因原子间堆叠导致有效活性位点不足。近年来,具有单位点、100%原子利用率及特殊电子结构的单原子催化剂(SACs)受到广泛关注,有望提高反应催化效率。总结了SACs的合成策略,梳理了其近年来在CO2还原、CH4部分氧化及有机物降解等环境领域的应用,并对其未来发展进行展望。
In today's increasingly severe pollution scenario,environmental catalytic technology is becoming more and more important.The catalytic performance of catalyst is closely related to its active sites.The traditional nano-catalysts have insufficient active sites due to the stacking of atomic structures.In recent years,with isolated active sites,100% atomic utilization efficiency and special electronic structure,the single-atom catalysts (SACs) have been widely concerned and are expected to further improve the catalytic efficiency of the reaction.In this paper,the synthesis methods of SACs were reviewed.The applications of SACs in the environmental fields,such as CO2 reduction,partial oxidation of CH4 and degradation of organic pollutants,were systematically combed,and the future development of SACs was looked forward to.
