| 摘 要： | 采用离子交换-沉积法，制备出CdS／Al-MCM-41负载型光催化剂（CdS／M41），利用UV—Vis、XRD、ICP—AES和SEM—EDS等测试手段对催化剂进行了表征。分析结果表明，CdS已进入Al-MCM-41孔道内；CdS为六方晶系，CdS的引入没有改变沸石骨架的有序结构及其形貌特征；UV—Vis吸收边出明显蓝移，是量子尺寸的体现。考察了不同反应介质中，CdS／M41光催化分解硫化氢制氢性能。实验结果表明，以0．35mol／LNa2S～0．25mol／LNa2SO3的混合水溶液为反应介质时，CdS／M41光催化产氢速率可达43．96mmol／g·h cat．（CdS），是纯CdS光催化剂的9．85倍。

| Abstract: | CdS nanoparticle loaded in the pore of Al-MCM-41 zeolite(CdS/M41) was prepared by ion exchange & precipitation method,and the crystalline structure of CdS/M41 was characterized by XRD,UV-Vis,ICP-AES and SEM-EDS.The XRD results revealed that the hexagonal structure peaks corresponding to CdS were obviously found in the pattern of CdS/M41,which was good for photocatalytic reaction.A blue shift of CdS absorption edge compared to the bulk CdS was found in UV-Vis.The framework and morphology of Al-MCM-41 zeolite... |
