Abstract:

采用高温固相法合成铅掺杂的K2Ti4–xPbxO9，微波辅助通过酸交换、胺柱撑、离子交换等步骤制备了硫化镉(CdS)插层的K2Ti4–xPbxO9(CdS-K2Ti4–xPbxO9)复合光催化剂。催化剂的结构利用X射线粉末衍射、紫外–可见漫反射吸收光谱和X射线光电子能谱等进行表征。考察了CdS-K2Ti4–xPbxO9在紫外光及可见光下催化制氢活性。催化剂的可见光吸收范围在Pb掺杂和CdS插层共同作用下得到了扩展，光催化活性也随之提高。催化剂在紫外光和可见光下3h产氢量分别为150.43mmol/(gcat)和2.43mmol/(gcat)。最后对光催化机理进行了分析。
