| 英文摘要 | tio2 nanotubes were prepared by hydrothermal treatment of tio2 powder in naoh aqueous solution and then calcined at various temperatures. the post-calcination treated tio2 nanotubes were decorated with cds by wetness impregnation and subsequently sulfurization to fabricate cds/tio2 composites. the photocatalytic performance of cds/tio2 composites toward hydrogen production from water splitting was investigated. the results show that the calcination temperature of tio2 nanotubes has a significant effect on the photocatalytic performance of cds/tio2. with the increase of calcination temperature from 300 to 500 degrees c, the crystallinity of tio2 nanotubes is increased resulting in the enhanced photocatalytic performance of cds/tio2. when the calcination temperature is higher than 500 degrees c, tio2 nanotubes gradually transform into nanorods and finally completely collapse, which leads to the decrease of photocatalytic performance of cds/tio2. the cds/tio2 composite with tio2 nanotubes calcined at 500 degrees c exhibits the highest hydrogen evolution rate, which could be attributed to its 1 d nanotubular structure and good crystallinity.
