摘　　要：以载银活性炭颗粒负载TiO2作催化剂,在紫外光照射下降解甲醛气体,考察了微波特殊场处理、紫外光光强、TiO2负载量及反应时间等主要因素对甲醛光催化降解率的影响,并考察了催化剂在反复使用后的失活情况。Adsorption and degradation properties of TiO_2-ACF-Ag under UV-light was studied. The main controlling factors which affected the degradation rate of formaldehyde such as the microwave irradiation, the intensity of UV-light, the capacity of TiO_2 load- ed and the reactive time were discussed. Then the deterioration of the catalyst activity after long term of use was obvious.
