摘要：

This paper reported the potential of heterogeneous photocatalysis as an advanced oxidation technology for NO, removal from vehicle emissions by using TiO2 as a photocatalyst immobilized on the surface of asphalt road. Based on asphalt road material porous characteristic, we utilized permeability technology to make asphalt nano-TiO2 to be environmental protection materials. And then using scanning electron microscope, we observed the penetrating effect of TiO2. The effect of surface friction, humidity and light intensity on NO, removal had been systematically investigated by the use of TiO2 immobilized on the surface of asphalt road as photocatalytic environmental protection materials. In addition, the decontaminating effect was tested by contrast test in TiO2 spraying section with non-spraying section, while the productions were used in road environment. Results of experiment revealed that decontaminating rate of the productions ranged from 6% to 12% this kind of photochemical catalysis environmental protection material has good environment purification function.
