Abstract
Photocatalyst has long been studied and used as a promising agent for reduction of air pollution, as it carries such useful characteristics as self-cleaning and powerful oxidation, and it leaves non-toxic by-products. Photocatalysis is a surface reaction and is initiated by absorbing light in the UV wavelength range, therefore the system efficiency is strongly dependent upon surface area and UV intensity. Until recently application of photocatalyst has been limited to low air flow rate with low concentration of pollutants since it has been very difficult for a compact system to provide the large surface area as well as the strong UV intensity. In this study, a very compact and innovative system with a honeycomb monolith substrate coated with photocatalyst and non- thermal plasma as an UV light generation source is suggested to obtain larger specific surface area and stronger UV intensity to effectively enhance the efficiency of photocatalysis. Using this system, parametric study has been made to determine the functional dependency of UV intensity and electric power consumption on such factors as supplied voltages, substrate lengths, air flow conditions and photocatalyst loading ratios.
