以杉木木粉经苯酚液化、熔融纺丝、固化处理、二氧化碳活化后获得的木质活性炭纤维为载体，采用溶胶-凝胶法制备木质活性炭纤维负载纳米 TiO2(WACFs/TiO2)光催化复合材料．研究光照时间、WACFs/TiO2催化剂用量、纳米TiO2负载量和初始甲醛质量浓度对WACFs/TiO2降解甲醛效果的影响．结果表明：随着光照时间、催化剂用量、初始甲醛质量浓度的增加，WACFs/TiO2对甲醛的降解率逐渐增加，但催化剂用量对甲醛降解率的影响相对较小；随 TiO2负载量的增多，WACFs/TiO2对甲醛的降解率呈现先增加后减小的趋势．当光照时间7,h、催化剂用量0.5,g、纳米 TiO2负载量29.89%、初始甲醛质量浓度8.82,mg/L时，WACFs/TiO2对甲醛的降解率达到92.33%．

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%.
