英文摘要	photocatalytic h-2 production on mos2/cds photocatalysts in the presence of different sacrificial reagents under visible light (lambda > 420 nm) has been investigated. the transformation process of the mo species loaded on cds, together with the junctions formed between mos2 and cds, was clearly demonstrated with x-ray photoelectron spectroscopy and transmission electron microscopy. photocatalytic h-2 evolution was optimized for mos2/cds catalysts. the 0.2 wt % mos2/cds catalyst calcined at 573 k achieves the highest overall activity for h-2 evolution, and the 0.2 wt % mos2/cds catalyst demonstrates even higher activity than the 0.2 wt % pt/cds, irrespective of different sacrificial reagents used. the junctions formed between mos2 and cds play an important role in enhancing the photocatalytic activity of mos2/cds catalysts. electrochemical measurements indicate that mos2 is an excellent h-2 evolution catalyst, which is another very important factor responsible for the enhancement of the photocatalytic activity of mos2/cds catalysts.
