Copper Oxide a Efficient Visible Light Photocatalyst For Dye Degradation

Abstract

CuO nano powder was prepared by a simple synthetic route involving hydrothermal method at 120 °C, and that was characterized by number of techniques, such as XRD, FESEM, and UV-vis DRS. UV-vis DRS and showed a reflection edge with corresponding energy at 2.2 eV. The photocatalytic degradation activity of the CuO nano powder was tested against the elimination of MB dye under sunlight exposure. About 65% degradation of MB dye is observed in 150 min.
