摘要
As a green, pollution-free, and renewable clean energy source, photocatalytic H2 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 H2 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 H2 generation rate of as high as 24.98 μmol h–1 mg–1, which is 11 times higher than that of the CdS-Cd nanoparticles (2.26 μmol h–1 mg–1), and it is superior than that of the CdS (1.51 μmol h–1 mg–1).
