摘要：

Low-cost photocatalysts of CdS combined with nickel oxides were prepared by a simple in situ photodeposition method. The activity of photocatalytic hydrogen evolution under visible-light (lambda > 400 nm) on CdS was enhanced significantly by loading nickel oxides, and reached to the maximum rate of 445.6 mu mol h(-1), being about 41 times and 1.9 times of the H-2 evolution on pure CdS and CdS loaded with 1.5 wt.% Pt, respectively. The characterizations of X-ray photoelectron spectroscopy and transmission electron microscopy with energy dispersive spectrometer indicated that the nickel oxides were loaded on CdS particles in the formation of Ni2O3 species, which acted as electron traps and facilitated the charge separation.
