用纳米级二氧化钛催化降解室内污染气体的实验

Studies on the Degradation of Indoor Air Pollution by Nanometer Grade Titanium Dioxide Photocatalyzing

设计了一个模拟室内环境污染的反应箱,对主要环境污染物:苯、甲醛、氮氧化物、硫氧化物等,在二氧化钛光催化剂作用下的降解效果进行了定量测量。实验结果表明:如在室内墙壁上喷涂适量的二氧化钛微粒,在光催化下能有效地降低污染气体的浓度。

Through devising reaction box to study environment aerial pollution like C_6H_6, HCHO, NH_3, NO_x, SO_2 etc. and accurately measuring the results of photocatalyzing degradation, it is shown that to spread grade nanometer titanium dioxide particles on the wall can degrade effectively the concentration of contaminative gases.
