Carbonyl-linked cobalt polyphthalocyanines as high-selectivity catalyst for electrochemical CO2 reduction

One type of carbonyl-linked cobalt polyphthalocyanine (CL-CoPPc) is synthesised as catalysts for use in electrochemical carbon dioxide (CO2) reduction (ECR). Carbonyl linkages can decrease the intermolecular π–π stacking, and serve as intramolecular “gullies” to impede proton transfer and the hydrog...

Zusammenfassung:One type of carbonyl-linked cobalt polyphthalocyanine (CL-CoPPc) is synthesised as catalysts for use in electrochemical carbon dioxide (CO2) reduction (ECR). Carbonyl linkages can decrease the intermolecular π–π stacking, and serve as intramolecular “gullies” to impede proton transfer and the hydrogen evolution reaction (HER). Therefore, the CL-CoPPc exhibits highly active and selective CO2 reduction to carbon monoxide (CO).
