Abstract
A method for direct application of a catalyst to a substrate for treatment of atmospheric pollution including ozone. The method includes applying a catalytic metal to a substrate utilizing a kinetic spray process. The process can be utilized to apply a base metal such as copper to a substrate and the base metal becomes the catalytically active oxide following application to the substrate. This system replaces a multi-step process with a single step process to provide a catalytically active surface that can be utilized to reduce ground level ozone and other atmospheric pollutants.
