空气中NO₂和SO₂的光催化反应动力学实验研究

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.
