Research Abstract

Co-loading Ag and CuO on WO_3 nanoparticles drastically enhanced the decolorization of Acid Red 88 dye molecule in aqueous solution under visible light irradiation. In addition, tungsten oxide nanotubes(WO_3NTs) with a large surface area were synthesized through a simple hydrothermal method. Comparative studies indicated that the photocatalytic activity of the Ag/CuO/WO_3NTs sample was much superior to that of bare-WO_3, Ag/CuO/WO_3, N-TiO_2 under the same conditions.
