The hydrogen evolution rate of the optimized catalyst was 9.51 mmol·g–1·h–1, indicating a nearly fivefold improvement over ZnCdS.
Material characterization confirmed the existence of ohmic contact, facilitating efficient movement of charge carriers.
Utilizing the physical stirring method, this study constructs an inorganic–inorganic heterojunction to enhance photocatalytic efficiency.
The stability observed after four cycles, maintaining 94.52% of initial activity, highlights the effectiveness of interfacial electronic coupling.
