| 中文摘要: |
| 本文通过水热辅助水浴法制备了CdIn2S4/ZnO复合材料,并采用XRD、XPS、UV-Vis/DRS、SEM、N2吸附-脱附等测试技术对复合材料的晶形结构和表面物理化学性质进行了表征。结果表明,相比于单体ZnO,微球形复合材料CdIn2S4/ZnO晶型结构更加优异,孔径分布更加均匀,比表面积明显增大,其光吸收范围拓展至可见光区。多模式光催化降解染料亚甲基蓝的实验结果显示,微球形复合材料CdIn2S4/ZnO的光催化活性优于单体ZnO和CdIn2S4,其中CdIn2S4与ZnO的比例为1：5时活性最好,其对不同有机污染物均具有光降解能力；另外,光解水制氢实验结果显示,在8 h内产氢量达到310.2 μmol/g,表明该复合材料具有优异的光解水制氢性能。 |
| 英文摘要: |
| CdIn2S4/ZnO composites were prepared by hydrothermal assisted water bath method, and the crystal structure and surface physicochemical properties of the composites were characterized by XRD, XPS, UV-Vis/DRS, SEM, N2 adsorption-desorption techniques. The results show that compared with monomer ZnO, the crystal structure of microsphere composites CdIn2S4/ZnO is better, the pore size distribution is more uniform, the specific surface area is obviously increased, and the optical absorption range is extended to the visible light region. The results of multi-mode photocatalytic degradation of methylene blue show that the photocatalytic activity of microsphere composite CdIn2S4/ZnO is better than that of monomer ZnO and CdIn2S4. The ratio of CdIn2S4 to ZnO is 1:5, and the photodegradation ability of different organic pollutants is the best. In addition, the results show that the hydrogen production reaches 310.2 μmol/g within 8 h, which indicates that the composite has excellent performance of hydrogen production by photolysis of water. |
