光催化降解甲醛的初步研究 |
| 齊文剛; 鄒麗霞(東華理工學(xué)院應用化學(xué)系; 江西撫州) |
| 摘 要：通過(guò)使用自制的光催化劑(二氧化鈦、三氧化鎢)分別負載在玻纖上,對甲醛氣體進(jìn)行 光催化降解。實(shí)驗結果表明:以靜態(tài)法考察了溫度,濕度對光催化降解甲醛的影響;實(shí)驗結果表明: 隨著(zhù)溫度、濕度的升高,光催化降解甲醛氣體的降解率先升高后降低;并對WO3/TiO2/玻纖光催化降 解甲醛的反應動(dòng)力學(xué)進(jìn)行了初步研究。 |

| Study on the Photocatalytic Degradtion of Formaldehyde |
| QI Wen-gang; ZOU li-xia Department of Applied Chemistry; East China Institute of Technology; Fuzhou 344000; China |
| 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 ... |
