摘要

As a green, pollution-free, and renewable clean energy source, photocatalytic H-2 production has attracted great attention. Here, epitaxial growth of pyramidal CdS-Cd nanoparticles on S-doped MoO2 nanosheets (CdS-Cd/S-MoO2) was prepared by one-step co-sublimation of CdS and MoO3. The photogenerated electrons of CdS as a photocatalyst are transferred to Cd and S-MoO2 as co-catalysts for H-2 production, which is observed by surface photovoltage (SPV) under visible light irradiation. At last, the obtained CdS-Cd/S-MoO2 presented an efficient photocatalytic performance under the visible light (>420 nm) with a prominent H-2 generation rate of as high as 24.98 mu mol h(-1) mg(-1), which is 11 times higher than that of the CdS-Cd nanoparticles (2.26 mu mol h(-1) mg(-1)), and it is superior than that of the CdS (1.51 mu mol h(-1) mg(-1)).
