Abstract
Based on vehicle emissions of decontamination by using nanometer titanium dioxide of photocatalysis method, we had optimized test about content of nano-TiO2 and surfactant and utilized permeability technology to make environmental protection materials of concrete nano-TiO2, consequently decontaminate vehicle emissions. On this foundation, we tested degradation effect of nanometer titanium dioxide in simulation road surface by a kind of testing system that it was designed by us. Results of experiment revealed that decontaminating rate of the productions ranged from22% to 48% this kind of photochemical catalysis environmental protection material has good environment purification function.
