采用微波辅助通过酸交换、胺柱撑、离子交换等步骤制备了CdS插层的K2La2Ti3O10(记做CdS-K2La2Ti3O10)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),紫外-可见漫反射吸收光谱(UV-Vis)和光致发光光谱(PL)等对产物进行表征,考察了CdS-K2La2Ti3O10在紫外光及可见光下催化制氢活性.结果表明,微波辅助法与传统法制备的插层复合催化剂晶型结构相似,同时大大减少了离子交换反应时间,减少了对层间结构的破坏,拓展了催化剂的可见光吸收范围.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221.53 mmol/(g cat.)和3.23 mmol/(g cat.),并对光催化机理进行了分析. The CdS-intercalated K2La2Ti3O10 (denoted as CdS-K2La2Ti3O10) composite photocatalyst was prepared by microwave-assisted acid exchange, amine pillaring and ion exchange etc. The structure of the composite photocatalyst was characterized by X-ray powder diffraction (XRD), field emission scanning electron microscope (SEM) , UV-Vis and PL spectra were used to characterize the product, and the catalytic activity of CdS-K2La2Ti3O10 for hydrogen production under UV light and visible light was investigated. The results showed that the microwave-assisted method and the traditional The crystal structure of the intercalated composite catalyst prepared by the method is similar, and the ion exchange reaction time is greatly reduced, the damage to the interlayer structure is reduced and the visible light absorption range of the catalyst is broadened. The microwave assisted catalyst prepared under ultraviolet light and visible light irradiation 3 Hydrogen production was 221.53 mmol / (g cat.) and 3.23 mmol / (g cat.) respectively, and the photocatalytic mechanism was also analyzed.
