摘要:

分子筛由于具有规则的微孔孔道结构、 较大的表面积、 优异的(水)热稳定性, 被认为是限域合成超小尺寸金属物种的理想载体. 近年来, 分子筛限域单原子金属催化剂由于超高的金属分散度、 接近100%的金属利用率以及独特的电子结构, 被广泛地应用于重要的催化反应和气体吸附分离过程. 本文系统地总结了近年来分子筛限域不同类型单原子金属催化剂的合成策略, 以及其在多相催化和气体分离等领域的研究进展. 最后, 提出了分子筛限域单原子金属催化剂在合成与表征方面存在的挑战和未来的发展方向.

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
