Abstract

采用硬脂酸法合成K 2 La 2 Ti 3- x Pb x O 10 , 通过微波辅助酸交换、胺柱撑、离子交换等步骤制备了CdS插层的K 2 La 2 Ti 3- x Pb x O 10 (记作CdS-K 2 La 2 Ti 3- x Pb x O 10 )复合光催化剂. 利用X射线粉末衍射(XRD), 场发射扫描电子显微镜(SEM), X射线能谱仪(EDX), 紫外–可见漫反射吸收光谱(UV-Vis), X射线光电子能谱(XPS)和光致发光光谱(PL)等对产物进行表征, 考察了CdS-K 2 La 2 Ti 3- x Pb x O 10 在紫外光及可见光下催化制氢活性. 结果表明, Pb离子掺杂和CdS插层K 2 La 2 Ti 3- x Pb x O 10 拓展了催化剂的可见光吸收范围, 提高了光催化活性. 微波辅助制备的催化剂在紫外光和可见光照射3 h后的产氢量分别为 230.15和3.35 mmol/(g cat), 并对光催化机理进行了分析.
