| 摘 要： | 对纳米TiO2掺杂金属盐后的光催化甲醛降解性能进行了试验研究.研究结果表明:适当钒掺杂改性提高了纳米TiO2降解甲醛的能力,经过钒掺杂改性纳米TiO2后其可见光范围的吸收明显增强;0.5? 0.3%V复合掺杂改性具有较好的光催化效果,比单一金属元素掺杂效果好,其甲醛降解率可达85%以上.

| Abstract: | The formaldehyde degradability by nanometer TiO_2 that is metal-doped compound was studied.The result shows that the formaldehyde degradability and the visible light absorbency are improved by the V-doped nanometer TiO_2.The nanometer TiO_2 of 0.5 % Fe+0.3 % V doped has better photocatalytic activity than single V-doped nanometer TiO_2.And it can degrade 85 percent formaldehyde after 24 hours. |

| Keywords: | nano-TiO_2 photocatalytic activity doped formaldehyde degradation |
