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

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.
