Flexible control of Co/Zn–nitrogen coordination in ZIFs for electrochemical CO2 reduction to tunable syngas

Bimetallic Co_xZn_y-ZIF catalysts were synthesized with adjustable Co/Zn-nitrogen sites for the electrochemical CO₂RR to tunable syngas, resulting in a H₂/CO ratio ranging from 1 : 1 to 4 : 1. The excellent CO₂ adsorption capacity and large specific surface areas were responsible for the high activity of all these Co_xZn_y-ZIF materials. This work has the potential to drive advancements in both the MOF application sector and electrochemical CO₂ reduction.
