Herein, a series of carbocatalysts containing Ru-based clusters have been prepared by the assistance zeolite–imidazolate frameworks (ZIFs). The introduction Ru is based on adsorption well-defined Ru3(CO)12 within cavity ZIFs following decomposition at 900 °C. Moreover, without breaking skeleton and porosity ZIFs, as-generated species would bond with Co nodes in situ to form bimetallic Ru–Co if Co-bearing metal–organic were utilized as host. Within confined space assembly could be rationally designed, their structures sophisticatedly controlled atomic scale. Among these compositions, clusters@N–C exhibited remarkable catalytic activity for NH3 H2 synthesis versus NPs@N–C, clusters@N–C, NPs@N–C. This study may open up new routine synthesize metallic or other subnano confinement ZIFs.
