Photodegradation of methyl orange dye by using Zinc Oxide – Copper Oxide nanocomposite
Abstract
The principal objective of this study was to synthesize, characterize and investigate the photocatalytic activity of Zinc Oxide - Copper Oxide nanocomposite for photocatalytic degradation of methyl orange dye under Ultraviolet irradiation. Co-precipitation method was used to synthesize the photocatalysts. Characterization of the crystal structure and phase state, the functional groups, analysis of the metals and band gap energy were determined by using different spectrophotometric methods. Also the photocatalytic activity of the nanocomposite was investigated by using Ultraviolet Visible spectrophotometer through irradiation of Ultraviolet lamp. The findings of this study indicated that the optimum photodegradation efficiency of the composite for the removal of Methyl orange was 92.18%at the optimized concentration of 0.3 gm of the catalyst, at pH of 8 and contact time of 120 minutes. In general, Photocatalysis might have effective degradation efficiency for organic dyes so as to remediate the environment from contamination of industrial wastes.
