Reaction Kinetics and Mechanism of Photocatalytic Degradation of Gaseous Toluene
气相甲苯光催化降解反应动力学及机理

Chemical kinetics and intermediates in photocatalytic degradation of gaseous toluene were investigated under UV irradiation with TiO2. According to the intermediates analyzed by GC/MS, possible mechanism for photocatalytic degradation of gaseous toluene was proposed. The result showed that the degradation of toluene followed the first-order chemical kinetics. With the increase of initial toluene concentration, the reaction rate of photocatalytic degradation of toluene increased and the reaction rate decreas...
