Abstract

CdS/Ba_1-xZn_xTiO₃ heterostructured photocatalysts were developed as a highly efficient and stable system for photocatalytic evolution of hydrogen from water splitting. In the system, CdS not only functions as photosensitizer to absorb visible light, but also participates with Ba_1-xZn_xTiO₃ for the generation of heterojunctions that block the recombination of photogenerated electrons and holes. The photocatalysts show excellent activity and stability, giving a high H₂ production rate of 1473μmolh^-1g^-1 under the irradiation of simulated solar light in a test period of 480h without loading any noble metal as cocatalyst or any reagents for regeneration. This study demonstrates that the development of CdS nanoparticles as photosensitizer is feasible for the photocatalytic H₂ production.
