A non-noble metal MoS 2 –Cd 0.5 Zn 0.5 S photocatalyst with efficient activity for high H 2 evolution under visible light irradiation

Zn x Cd 1−x S solid solutions with uniform sizes and shapes were synthesized. Subsequent loading of MoS 2 to one solution yielded a highly-active MoS 2 –Cd 0.5 Zn 0.5 S noble-metal-free photocatalyst; the highest H 2 evolution rate was 12.30 mmol h −1 g −1 from water under visible light irradiation.
