Abstract

Photocatalytic degradation of methylene blue dye (MB) was in aqueous solution using untreated TiO2 and TiO2/polyamide 11 (TiO2/PA-11) under visible light irradiation. The effects of catalyst loading and pH values on the dye degradation were studied. An aqueous solution of MB was degraded by more than 95% with TiO2/PA-11 (200 ppm) after visible light irradiation at 360 min. However MB dye was degraded by more than 99% for 180 min with TiO2/PA-11 at pH 10
