光催化降解甲醛的初步研究 |
| 齐文刚; 邹丽霞(东华理工学院应用化学系; 江西抚州) |
| 摘 要：通过使用自制的光催化剂(二氧化钛、三氧化钨)分别负载在玻纤上,对甲醛气体进行 光催化降解。实验结果表明:以静态法考察了温度,湿度对光催化降解甲醛的影响;实验结果表明: 随着温度、湿度的升高,光催化降解甲醛气体的降解率先升高后降低;并对WO3/TiO2/玻纤光催化降 解甲醛的反应动力学进行了初步研究。 |

| Abstract：In this test, formaldehyde was degraded by self-prepared photocatalyst (TiO2,WO3 deposited on fiberglass) .The effects of the three photocatalysts were contrasted by degrading formaldehyde. We studied degradation rate of formaldehyde in the different activation temperature and different humit. The results showed that photocatalytic degradation rate of formaldehyde was first up and then down with temperature and humit rising . the study on the relation between photocatalytic degradation rate of formaldehyde ... |
