제목 Synthesis of poly(vinyl alcohol)/poly(acrylic acid)/ TiO2 composite hydrogels and their photobleaching properties
초록 The pH-sensitive photocatalytic system was prepared by embedding TiO2 into poly(vinyl alcohol)/poly(acrylic acid) hydrogel. Two different types TiO2/hydrogel composites, such as matrix and nanofiber, were prepared to investigate the morphological effects on the photocatalytic activity. The photocatalytic efficiency was tested on the target pollutants by UV/VIS spectrophotometer at 385nm. X-ray diffraction was used to determine the crystallinity. The photobleaching of dye was improved greatly as the pH was changed into basic condition and the larger surface area of hydrogel was available for TiO2 by using nanofibrous supports.
