Mn掺杂TiO2负载木质活性炭纤维可见光降解甲醛的研究
Visible Light Photodegradation of Formaldehyde with Mn-doped TiO2 Loaded on Wood-based Activated Carbon Fibers
摘要
Abstract
Mn-doped TiO2 loaded on wood-based activated carbon fibers(Mn/TiO2-WACFs)was prepared with WACFs as the support. The effects of Mn doping concentration,lighting time,illumination intensity,initial formaldehyde concentration and Mn/TiO2-WACFs doses on formaldehyde degradation rate under visible were studied. The results showed that when increasing lighting time,Mn/TiO2-WACFs doses and initial formaldehyde concentration,the degradation rate of formalde-hyde increased gradually;when increasing Mn doping concentration and illumination intensity,the degradation rate of for-maldehyde first increased and then decreased. When 65,W spiral energy saving lamp lighting reached 4,h,the initial formal-dehyde concentration was 9.38,mg/L,n(Mn)∶n(Ti)=1∶100,and Mn/TiO2-WACFs dose was 0.22,g,the degradation rate of formaldehyde reached 91%,.关键词
