Efficient visible-light-driven photocatalytic hydrogen production over a direct Z-scheme system of TaON/Cd_0.5Zn_0.5S with a NiS cocatalyst

In this work, a study on the photocatalytic evolution of H2 showed that the direct Z-scheme T4-ZCS with 0.5 wt% NiS cocatalyst could reach the highest H2 evolution rate of 34.8 mmol h−1 g−1 with a quantum yield of about 25.5%.
