Publication: Journal of Materials in Civil Engineering
Volume 31, Issue 8
Abstract
Automobile exhaust emission has become one of the environmental problems that cannot be ignored. In order to improve the photocatalytic activity of titanium dioxide (), graphitic carbon nitride was prepared, and its bonding state and morphology were analyzed by microscopic characterizations. The nitric oxide (NO) removal efficiency of was higher than that of and . This was attributed to the formation of a heterojunction between and which accelerated the separation and transfer of photoinduced carriers. Because the results showed that the micropores produced by demulsification of emulsified asphalt were beneficial to the improvement of photocatalytic performance, emulsified asphalt was chosen as the carrier of photocatalysts to study the influence of different application forms on photocatalytic performance of asphalt specimens. Furthermore, it was found that both the specimens with spraying photocatalyst aqueous solution and the specimens with spreading powder had a good NO removal effect. However, with the increase of photocatalyst content, the NO removal efficiency of sprayed specimen was higher than that of the spreading specimen due to the good dispersion of the photocatalyst in the spraying solution.
