Carbon Coated TiO₂ and it Application on Photodegradation of 4-Chlorophenol under Solar Irradiation

Abstract:

The photocatalytic degradation of 4-Chlorophenol (4CP) using carbon C coated TiO₂ (C-TiO₂) and pristine TiO₂ under solar irradiation was carried out in a suspension mode under custom made glass cell reactor with continuous aeration supply. It was found that 0.3 and 0.6 g were the optimum loading for C-TiO₂ and pristine TiO₂ respectively in the degradation of 20 mg L^-1 4CP under solar irradiation. The optimum C-TiO₂ was found six times faster than pristine TiO₂ based on pseudo first order rate constant of 4CP photodegradation. No adsorption was observed in the photocatalysts. The intermediates observed during this photocatalytic degradation process were maleic acid, hydroquinone (HQ), benzoquinone (BQ), 4-chlorochetol (4CC) and resorcinol.
