摘要：
The CdS/TiO2 photocatalytic composites containing different amounts of CdS were fabricated using sol-gel method with P25 TiO2 as the raw material. The obtained CdS/TiO2 was further modified by multi-wall carbon nanotubes (MWCNTs). The as-synthesized MWCNTs/CdS/TiO2 photocatalytic composites were characterized by scanning electron microscopy, low temperature nitrogen adsorption-desorption (BET surface area) and hydrogen evolution from water photo-splitting. The influence of MWCNTs on the photocatalytic hydrogen evolution performance for CdS/TiO2 catalysts was investigated using Na2S-Na2SO3 as a sacrificial electron donor under UV-Vis light irradiation. It is found that hydrogen production(14.0 mu mol) from water photo-splitting can be enhanced by introducing MWCNTs into CdS/TiO2 composites, in comparison to CdS/TiO2 photocatalysts(11.6 mu mol). The average hydrogen production rate can be improved by 18% and the highest rate improvement can be up to 21%.
