Illustration showing the synthetic route to Au25@M-MOF-74 (M = Zn, Ni, Co, and Mg) for enhanced catalysis through microenvironment modulation around Au25(Cys)18 by adjusting the metal nodes on MOF pore walls.

Caption

Based on the coordination self-assembly and electrostatic interactions, Au25(Cys)18 nanoclusters were encapsulated into the representative multivariate MOFs, M-MOF-74 (M = Zn, Ni, Co, Mg), under ambient temperature and alkaline aqueous solution conditions. It was found that by altering the metal nodes of MOF-74, the microenvironment of the Au25(Cys)18 nanoclusters could be effectively modulated, thereby enhancing their catalytic performance.
