Abstract

The study is devoted to influence of atmospheric corona discharge on the course of photocatalytic oxidation of vapors of acetone (83 ppm), acetaldehyde (108 ppm), and toluene (12-46 ppm) over TiO2 under the action of soft ultraviolet (UV) light in a closed chamber. Corona discharge was created around the wires of the charging section of an electric precipitator situated upstream of a photocatalytic filter. Substantial acceleration of removal and deep oxidation of the compounds into CO2 is revealed, the highest effect being observed for acetaldehyde. In the presence of corona discharge, the rate of deep oxidation per unit of consumed electric power was shown to increase by a factor of 1.2-3.6. The results point out to promising prospects of combining photocatalytic and plasma-chemical oxidations for purification of gas exhausts.
