Abstract

A photocathode for CO2 reduction was successfully developed using a hybrid electrode comprising a Ru(II)-Re(I) supramolecular photocatalyst and a NiO electrode. Selective photoexcitation of the Ru photosensitizer unit of the photocatalyst at -1.2 V vs. Ag/AgNO3 selectively afforded CO with high faradaic efficiency.
