Photoelectrochemical CO2 reduction using a Ru(ii)–Re(i) multinuclear metal complex on a p-type semiconducting NiO electrode†
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.
