木质活性炭纤维负载纳米TiO2降解甲醛的效果
Photocatalytic Degradation Effect of Formaldehyde on Wooden Activated Carbon Fibers Loaded Nano-TiO2
摘要
Abstract
Wooden activated carbon fibers loaded nano-TiO2(WACFs/TiO2)was prepared by sol-gel method and with WACFs as the support which was obtained from the phenolated Chinese fir after phenol liquefaction,melt spinning,and curing treatment through CO2,activation. The effects of lighting time,WACFs/TiO2,doses,loading rate of nano-TiO2and initial formaldehyde concentration on the degradation rate of formaldehyde with WACFs/TiO2 were studied. The results showed that with the increase of lighting time,WACFs/TiO2 dose and initial formaldehyde concentration,the degradation rate of formaldehyde gradually increased. With the increase of the loading rate of nano-TiO2,the degradation rate of formal-dehyde first increased and then decreased. When the lighting time was 7 h,the WACFs/TiO2 dose 0.5,g,the loading rate of nano-TiO229.89% and the initial formaldehyde concentration 8.82,mg/L,the degradation rate of formaldehyde reached 92.33%.关键词
