Abstract
Abstract A facile and cost-effective preparation of nanoscale TiO 2 with enhanced surface area was achieved through gel-combustion technique assisted via glycine as a fuel. X-ray diffraction studies confirmed the anatase phase and nanocrystalline formation of TiO 2 nanoparticles (NPs). Using N 2 adsorption-desorption curve, the enhanced surface area (54.3m 2 g −1 ) of TiO 2 NPs was noted. Visible light driven photocatalytic activity of the TiO 2 NPs for the degradation of Methylene Blue (MB) dye was studied. The complete degradation of MB dye under sunlight irradiation was achieved in 120min. All the outcomes show that prepared TiO 2 nanoparticles have excellent visible light driven photocatalytic activity for the active degradation of MB dye.
