Abstract

A solar to chemical energy conversion efficiency of 4.6% was demonstrated for CO2 photoreduction to formate utilizing water as an electron donor under simulated solar light irradiation to a monolithic tablet-shaped device. The simple CO2 photoreduction system was realized by exploiting the effect of the carbon substrate on selective CO2 reduction in the presence of oxygen and selective H2O oxidation over IrOx catalysts in the presence of formate.
