How does mass transfer influence electrochemical carbon dioxide reduction reaction? A case study of Ni molecular catalyst supported on carbon

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 CO₂transfer and therefore change the CO₂concentration at the surface of the catalyst, which singnificantly impacted the CO₂RR performance. © The Royal Society of Chemistry 2021.
