Title

Efficient Photocatalytic Degradation Of Methylene Blue With Cuo Loaded Nanocrystalline Tio2

Abstract

Nanocrystalline titanium dioxide (TiO2, anatase) is a promising material in solving various environmental problems because of its unique photocatalytic activity and high photoelectric performance. However, the photocatalytic activity of phase pure nanocrystalline anatase is low because of easy recombination of photoinduced holes and electrons. This research enhanced the photocatalytic efficiency of nanocrystalline anatase by loading with copper oxide (CuO). In this effort, a series of CuO loaded TiO2 photocatalysts were prepared and analyzed. The photodegradation of methylene blue solution in the presence of these photocatalysts under UV radiation was studied. The color of the methylene blue solution faded gradually with time indicating photocatalysis. Results showed that the photocatalytic activity of nanocrystalline anatase was enhanced by the addition of CuO till 20 wt% addition, after that the photocatalytic activity notably dropped. XPS results showed that the deposited copper formed Ti-O-Cu bond on the surface of TiO 2.
