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 IrO_x catalysts in the presence of formate.
