摘要
采用浸涂法在活性炭空气净化网上负载纳米二氧化钛 ,在紫外光的照射下 ,净化网对一氧化碳、甲醛、硫化氢等污染物的净化能力明显增强 ,对比实验表明 ,在紫外光照射下光催化剂使被吸附的污染物发生降解反应而提高活性炭的净化能力。活性炭的吸附作用为光催化反应提供高浓度环境 ,加速了反应速率。
Nano TiO 2 was dip coated on active air purification sieve of active carbon.The purification effect of this sieve against various polluting gases were investigated.The result showed that purification effects on H 2S,NH 3,HCHO,CO,and toluene were notably enhanced throush degradation of pollutants by photocatalysis agent under UV irradiation,which resulted in enhanced purification ability of active carbon. The adsorption effect of active carbon provided a high concentration environment to increase the reaction rate.
