Light‐Driven Syngas Production over Defective ZnIn ₂ S ₄ Nanosheets

Photocatalytic syngas (CO and H 2 ) production with CO 2 as gas source not only ameliorates greenhouse effect, but also produces valuable chemical feedstocks. However, traditional photocatalytic systems require noble metal or suffers from low yield. Here, we demonstrate that S vacancies ZnIn 2 S 4 ( V S ‐ZnIn 2 S 4 ) nanosheets are an ideal photocatalyst to drive CO 2 reduction into syngas. It is found that building S vacancies can endow ZnIn 2...
