Abstract

Abstract:

Atomically dispersed catalysts (ADCs) combine the advantages of both homogeneous and heterogeneous catalysts, with high specific surface area, high atomic utilization, and clear structure. They exhibit excellent catalytic performance while being easy to separate and recover. Therefore, they have received widespread attention in the field of industrial catalysis and are considered the most promising catalysts. This review categorizes and summarizes the general synthesis methods of atomic level dispersed catalysts. In addition, it investigates the catalytic applications of atomic level dispersed catalysts in selective hydrogenation, carbonylation, dehydrogenation and other chemical reactions. Finally, the opportunities and challenges faced by the current application of ADCs were summarized, providing reference for its future development and application.

Key words: atomically dispersed, catalyst, synthesis, chemical reaction
