Abstract

Highly selective photoelectrochemical CO₂ reduction (>80% selectivity) in water was successfully achieved by combining Cu₂ZnSnS₄ (CZTS) with a metal-complex electrocatalyst. CZTS, a sulfide semiconductor that possesses a narrow band gap and consists of earth-abundant elements, is demonstrated to be a candidate photoabsorber for a CO₂ reduction hybrid photocatalyst.
