Non-thermal plasma-induced photocatalytic degradation of 4-chlorophenol in water
Journal of Hazardous Materials 141(2007)475-482,-0001,():
TiO2 photocatalyst (P-25) (50mg L-1)was tentatively introduced into pulsed high-voltage discharge process for non-thermal plasma-induced photocatalytic degradation of the representative mode organic pollutant parachlorophenol (4-CP), including other compounds phenol and methyl red in water. The experimental results showed that rate constant of 4-CP degradation, energy efficiency for 4-CP removal and TOC removal with TiO2 were obviously increased. Pulsed high-voltage discharge process with TiO2 had a promoted effect for the degradation of these pollutants under a broad range of liquid conductivity. Furthermore, the apparent formation rates of chemically active species(e. g., ozone and hydrogen peroxide)were increased, the hydrogen peroxide formation rate from 1.10
