Synthesis and enhanced photocatalytic property of CuO nanostructure via dip coating method

There are variety of technique that being used for water treatment but photocatalytic activity is one of the most efficient and low cost method. In this paper, photocatalytic properties of nanostructures cupric oxide (CuO) has been investigated. CuO has a norrow bandgap energy of 1.2 eV. The nanostructures CuO were synthesized via dip coating method and characterized by field emission scanning electron microscopy (FESEM) to observed the surface morphology of the films. Photocatalytic experiments was carried out on sample of 60 cycles with 200 °C, 300 °C and 400 °C of annealing temperature due to their highest density and homogenous distributed on the substrate. Every sample have been exposed to solar simulator for 2.5 hours. Photocatalytic property was examined using ultraviolet-vis (UV-vis) spectrophotometer. The results showed that higher annealing temperature as well as longer exposured duration to the solar simulator exhibits enhanced photocatalytic performance.
