CdSe和TiO2复合后,其对可见光的利用率大大提高,光电性能和光催化性能都得到明显改善。对CdSe敏化TiO2的原理做了简要阐述,主要综述了CdSe/TiO2纳米复合材料的制备及性能,重点介绍了目前制备薄膜及粉体CdSe/TiO2纳米复合材料的方法和所得复合材料在光催化和太阳能电池领域中的应用研究,并对不同方法制备的材料的结构与特性作了简要对比。但目前这一复合材料仍存在缺陷,所以人们又对其进行了改性研究,也对这一方面作了简要介绍。因此,通过对CdSe或TiO2的形貌进行控制或改性来进一步提高复合材料的性能将是今后研究的重点,不能只偏重对其光电性能的研究,也要加大对其光催化性能的研究。
CdSe and TiO2 composite, its utilization of visible light greatly improved, the optical properties and photocatalytic properties have been significantly improved. The principle of CdSe sensitized TiO2 was briefly described. The preparation and properties of CdSe / TiO2 nanocomposites were reviewed. The methods of preparing CdSe / TiO2 nanocomposites and their applications in photocatalysis And solar cell applications in the field of research, and prepared by different methods of the structure and characteristics of a brief comparison. However, this composite material is still flawed at present, so people have carried on the modification research to it, also made a brief introduction to this respect. Therefore, it is the focus of future research to further improve the properties of CdSe or TiO2 by controlling or modifying the morphology of CdSe or TiO2. It should not only focus on its photoelectric properties, but also on its photocatalytic properties .
