Abstract

Photoelectrochemical reduction of CO₂ to HCOO⁻ was successfully achieved by a p-type InP photocathode modified with an electropolymerized ruthenium complex in water. This technique decreased the required applied potential for CO₂ reduction by utilizing solar energy. The carbon and proton sources of HCOO⁻ were identified by a tracer experiment to be CO₂ and H₂O, respectively.
