The Experimental Study on the Reaction Mechanism of Photocatalytic Air Purification

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.
