Effect of graphene oxide on photocatalytic properties of poly(vinyl alcohol)/poly(acrylic acid)/TiO2/graphene oxide nanocomposite hydrogels |
초록 |
The nanocomposites of hydrogel and graphene oxide (GO) were prepared for the treatment of aqueous pollutant. The nanocomposite hydrogels consisted of anatase TiO2, GO, and pH-responsive poly(vinyl alcohol) (PVA)/ poly(acrylic acid) (PAAc). To improve the photocatalytic properties of PVA/PAAc/TiO2 composite hydrogel, GO was used as an active ingredient. The photocatalytic activity of PVA/PAAc/TiO2/GO nanocomposite hydrogels was evaluated by UV spectrometer based on the degradation of two different model pollutants such as acidic and basic dyes. The improved removal of pollutant was due to the two-step mechanism based on the absorption of pollutants by nanocomposite hydrogel and the decomposition of pollutants by TiO2 and graphene oxide. The photocatalytic nanocomposite hydrogel was suitable as a promising system for the treatment of wastewater. |
