摘　　要：主要介绍了湿化学法原位合成碳纳米管-硫化镉(MWCNTs-CdS)复合材料,并考察了其光解水产氢性能。结果表明,碳纳米管能显著增强CdS光解水产氢性能,碳纳米管的添加量存在一个最佳值。当碳纳米管的含量为1%(质量分数)时,MWCNTs/CdS的产氢速率最高,在使用300W氙灯光源、不加Pt共催化剂的条件下达到205μmol·g^(-1)·h^(-1),产氢速率是单独CdS产氢速率的2倍多。该研究为开发高效光解水产氢催化剂提供了新的思路。The MWCNTs-CdS nanocomposites with various MWCNT contents are in-situ synthesized through a wet-chemical method. The photocatalytic water splitting properties for hydrogen evolution have been investigated. The results show that MWCNTs can enhance photocatalytic hydrogen generation efficiently. When the content of MWCNTs is optimized to lwt%, the highest rate of hydrogen evolution（205μmol · g^-1 · h^-1） is obtained, which is more than two times of that of bare CdS. This finding may offer a new idea to develop efficient catalysts for photocatalytic hydrogen generation.
