Abstract
In the past few years, carbon-based semiconductor nanocomposites have attracted great attention due to their unique combinations of chemical and physical properties. Incessant research interest has been devoted on preparing graphene-based TiO2 nanocomposites for photocatalytic application. The present study aims to examine the photocatalytic activity of graphene-titania nanocomposite prepared via hydrothermal method. For a comparison, the photocatalytic activity of pure titania was also investigated. The prepared systems are well characterized using XRD analysis, FTIR spectroscopy, UV-VIS diffuse reflectance spectroscopy, Transmission Electron Microscopy, Photoluminescense study and Surface area analysis by BET method. The Photocatalytic activity of the composite was studied by measuring the degradation of aqueous solution of Crystal Violet (CV) dye under UV and Visible light. Modification with graphene has commendably increased the photocatalytic activity of titania.
