Abstract:

Zeolites are considered as ideal supports for encapsulating ultrasmall metal species due to their uniform microporous channels, large specific surface areas, and excellent thermal stability. In recent years, thanks to the superhigh metal dispersion, nearly 100% metal utilization efficiency and unique electronic structure, zeolite-encaged single-atom metal catalysts have been widely used in many important catalytic reactions and gas adsorption/separation processes. In this review, we present a comprehensive summary of the state-of-the-art synthetic strategies of zeolite-encaged different kinds of single-atom metal catalysts and their applications in heterogeneous catalysis and gas separation. In the last part of this review, some future perspectives on the challenge and opportunity for this subject are pointed out. We hope that this review will provide reference for researchers to carry out more innovative research works in the future.

Key words: Zeolites, Single-atom, Heterogeneous catalysis, Confinement effect
