摘要: 为了研究污染物NO2和SO2的光催化降解规律,分析了不同污染物初始浓度对光催化降解效果的影响;采用反应速率这个衡量光催化反应进程的重要参数,通过实验发现污染物NO2、SO2的光催化氧化过程符合L—H反应动力学方程;实验证明,将催化剂与吸附性材料相结合可以提高室内污染物降解速率.Abstract: The effect of initial concentration of pollutant on the photocatalytic efficiency was analyzed to study the photodegradative rules of NO2 and SO2. The results shown that the kinetics of the photocatalytic oxidation of NO2 and SO2 fitted the L-H kinetic equation, which confirm that integrating the catalyst with absorbed materials can improve the efficiency of photocatalytic indoor air purification.
