Abstract

Electroreduction of carbon dioxide was homogeneously carried out using cofacial dinuclear metalloporphyrin CoTMPyP-MTPPS. The reduction was catalyzed by Co(I)TMPyP which generated at −1.8 V vs. Ag/Ag⁺. More excellent catalytic activity was observed in the presence of H₂O in comparison with that for mononuclear one. The catalytic activity depended on the central metal of TPPS because they worked as an electron mediator.
