Visible light driven photocatalytic activity of TiO2 nanoparticles prepared via gel-combustion process

Abstract

A facile and cost-effective preparation of nanoscale TiO2 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 TiO2 nanoparticles (NPs). Using N2 adsorption-desorption curve, the enhanced surface area (54.3m2g-1) of TiO2 NPs was noted. Visible light driven photocatalytic activity of the TiO2 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 TiO2 nanoparticles have excellent visible light driven photocatalytic activity for the active degradation of MB dye.
