文摘
- •
Platinized Cd1−xZnxS, Cd1−xZnxS/ZnO/Zn(OH)2, and Cd1−xZnxS/Zn(OH)2 were prepared.
- •
Transformations of samples during H2 evolution were studied by XRD and XPS.
- •
Activation during H2 evolution was observed for all multiphase photocatalysts.
- •
Pt/Cd0.6Zn0.4S was shown to exhibit a strong deactivation due to CdCO3 formation.
- •
Photocatalytic activity (λ = 450 nm) 3.4 mmol H2 g−1 h−1 was achieved.
