Multiobjective optimization of a g-C3N4/Cd-Zn3In2S6 heterojunction for high-efficiency photocatalytic hydrogen evolution

Zn 3 In 2 S 6 (ZIS) doped with Cd 2+ and heterojunction construction with g-C 3 N 4 (GCN) can synergistically improve photocatalytic activity. The photocatalytic H 2 production rate of 5% GCN/Cd/ZIS composite can reach 3.34 mmol g −1 h −1 .
