The Decontamination of Vehicle Emissions NOx through Functionality Surface of Concrete Road
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.
