Abstract

A series of heterogeneous molecular catalysts by immobilizing nickel(ii) phthalocyanine (NiPc) onto different carbon supports were constructed to study the influence of the catalyst's microstructure on the performance of electrochemical carbon dioxide reduction reaction (CO2RR). The microporous structure of the electrocatalysts could influence CO2 transfer and therefore change the CO2 concentration at the surface of the catalyst, which singnificantly impacted the CO2RR performance.
