It is an interesting topic to improve the photocatalytic H2 evolution activities of catalysts.In this parper,CdS nanospheres on titanium meshes have been synthesized by a simple hydrothermal method.The composition,microstructure and morphology of samples were investigated using X-ray diffractometer(XRD),scan electron microscopy(SEM),transmission electron microscope(TEM)and X-ray photoelectron spectroscopy(XPS).And the photoelectrochemical properties and photocatalytic properties under visible light were studied.The results show that,each CdS nanosphere on titanium meshes is self-assembled with nanorods.Then,the samples were used as photoelectrochemical photoanodes and photocatalytic water-splitting processes,the sample with a Cd/S amount of substance ratio of 1∶1(CdS-1)has a good photoelectric response,and has a maximal photocurrent of~140 μA.At the same time,the results show that the sample has a good H2 evolution activity with the rate of 212.6 pmol·h-1·cm-2 and recycling convenient,reusable,which can be an ideal photocatalyst.
