TiO2 being a wide band-gap material offers photocatalytic activity only in the UV region. The effects of simultaneously improving the surface area and nitrogen doping on the visible light-assisted photocatalytic activity of titanate-derived two-dimensional (2-D) sheets of TiO2 have been investigated. Results indicate a remarkable efficiency in the photocatalytic degradation of methyl orange in an aqueous environment when compared to undoped 2-D TiO2 sheets.
