Visible light-induced photocatalytic activity of high surface area N-doped two-dimensional (2-D) TiO sub(2) sheets

TiO sub(2) 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 TiO sub(2) 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 TiO sub(2) sheets.
