제목 Photocatalytic composites based on pH-responsive poly(vinyl alcohol)/poly(acrylic acid) hydrogels containing TiO2
초록 The photocatalytic film was prepared by using TiO2 (anatase type) and pH-responsive poly(vinyl alcohol)/poly (acrylic acid) hydrogel. The photocatalytic efficiency was measured by UV spectrometer based on the degradation of model pollutants. The pH-responsive degradation of pollutants was carried out with the photocatalytic film. The improved efficiency of pollutant removal was due to the two-step mechanism based on the absorbance and degradation of pollutants by ! hydrogel and TiO2, respectively. These photocatalytic composites were suitable as a promising system for the treatment of wastewater.
