Abstract
Photocatalysis is a promising technique for remediation of indoor air pollution. The present invention focuses on the enhancement of the effectiveness of the photocatalytic process by the introduction of artificial roughness on the interior reactor surface. Artificial roughness elements on the catalytic surface enhance the turbulence intensity close to the catalytic surface. The enhanced turbulence intensity translates to an increase in the mass transfer of airborne contaminants to the catalyst surface, improving the efficiency of photocatalysis.
