Abstract :
A floating polymer-supported photocatalyst based on polystyrene impregnated with titanium dioxide particles was developed using a facile solvent-cast method at ambient temperature. The prepared photocatalysts were characterized by X-ray diffraction, scanning electron microscopy and fourier transform infrared spectroscopy. The photocatalytic activity of the developed photocatalysts was investigated using methylene blue dye. The prepared polystyrene-supported titanium dioxide photocatalysts successfully removed color from the aqueous solution without any additional pH adjustment under ultraviolet (254 nm) irradiation and non-stirred, non-anchored conditions. The maximum color removal achieved by the optimized photocatalyst (10 weight percent loading of Degussa P25 with respect to amount of polystyrene) was around 93% after 7.5 h of ultraviolet light exposure. Further, the photocatalyst sheets were also tested for recovery and reuse. The efficiency of color removal achieved by the optimized photocatalyst on reuse was in the range of 99–100%. The developed photocatalyst seems to be a promising candidate that can be further investigated for large scale commercial applications.
