摘要
通过制备不同尺寸的CdS纳米颗粒~([1]),研究反应条件以及前驱物对其形貌、尺寸的影响,选择在可见光下性能较好的结构与具有独特结构和良好的氧化还原性的多金属氧酸盐K_6H_4~([α-SiW9O37~([Co_3(H_2O)]))_3·17H_2O(简称SiW9Co3)进行复合~([2])。根据CdS和SiW_9Co_3的带隙分析,CdS导带电子可从转移到SiW_9Co_3,而SiW_9Co_3的价带空穴则可转移到CdS,从而实现光生载流子在不同组分上的空间分离抑制它们的复合,提高材料的光催化制氢活性。
By preparing different sizes of CdS nanoparticles to study its morphology and size of the influence of the reaction conditions and precursors. We choose better performance structure of CdS nanocrystals with having a unique structure and good redox properties of metal-oxygen clusters compound complex under visible light. Here,we synthesized CdS-α-SiW_9 composite nanostructures and research on its photocatalytic hydrogen evolution performance in visible light.
