It’s no secret that inner city areas can get some bad air from motor traffic and industrial activity. Aside from getting everybody to stop driving, and turning off all the factories, there isn’t much to be done about bad city air. But new research conducted by experts at the Eindhoven University of Technology in the Netherlands could change that.
Using a photocatalytic spray coating on pavement, scientists have created a surface that eats air pollution. A photocatalytic substance – titanium oxide – is applied to the surface of the pavement, which then reacts with chemicals in the surrounding air. The pavement was found to reduce the amount of nitrogen oxide in the air by almost 45%.
The spray has great potential for application in densely populated urban areas, where air pollution is increasingly becoming a problem. The findings have been published in the Journal of Hazardous Materials.
