| 摘 要： | 为了提高室内环境空气质量，本论文开展了光催化剂制备的研究。本论文采用溶胶-凝胶法制备B／Y^3＋共掺杂TiO2复合光催化材料，以甲醛为降解物质，在紫外和可见光下分别研究了复合催化剂的光催化活性，对不同掺杂对光催化活性的影响、光催化剂的稳定性进行了分析。B／Y^3＋共掺杂TiO2复合光催化材料大大提高了催化剂的活性，对甲醛降解有较高的效率。

| Abstract: | In order to enhance the indoor environmental air quality, the preparation of photo - catalyst is studied. Through preparation of B/Y^3＋ jointly mixed by nanometer TiO2 catalytic materials with sol - gel method, adopted formaldehyde as degrading substance, the photo - catalytic activities of complex catalysts under ultraviolet and visible conditions are studied respectively. The impacts of different mixtures on photo - catalytic activities and stability of photo - catalyst are analyzed. The complex catalytic materials of B/Y^3＋ jointly mixed by nanometer TiO2 could enhance catalyst activities, and it has high efficiency to degrade formaldehyde. |
