Metal-Organic Framework-Templated Catalyst: Synergy in Multiple Sites for Catalytic CO2 Fixation

Abstract

The types and quantities of active sites play a critical role in catalysis. Herein, ZnO nanoparticles encapsulated into N-doped porous carbon has been rationally prepared by the pyrolysis of a metal-organic framework (MOF) followed by a moderate oxidation treatment. The resulting catalyst exhibits excellent activity, selectivity, and recyclability in the CO₂ cycloaddtion reactions with epoxides owing to the synergy of multiple sites inherited from the MOF and generated by the oxidation process.

Keywords: carbon; co2 fixation; doping; heterogeneous catalysis; metal-organic frameworks.
