摘要
Abstract
With the development of automobile industry, the tail gas of motor vehicles is one of major air pollution sources.Effects of nano-TiO2 photocatalytic oxidation immobilized on road surface materials on nitrogen oxides were investigated. Results show that the photocatalyst immobilized on concrete exhibits excellent photocatalysis, while the photocatalysis of bituminous mixture is poor. Differences between concrete and bituminous admixture as carriers in the adsorb-ability of molecule to air on surface, the light absorption and the light transmissibility are discussed. Moreover the mechanism model for photocatalytic oxidation of nitrogen oxides by supportive nano-TiO2 photocatalyst is put forward.关键词
