Review on the Photocatalytic Degradation of Dyes and Antibacterial Activities of Pure and Doped-ZnO

Tesfay W. Gebreslassie, Manjunatha Pattabi, Rani M. Pattabi

Abstract: This paper reviews the recent advances on the photocatalytic and antibacterial activities of ZnO, metal-doped ZnO, non metal-doped ZnO and nano-composite of ZnO synthesized using different methods. Materials with different morphologies and structures have been investigated, by different groups, under UV, visible light and sunlight irradiations. The majority of data reveal superior performance of modified ZnO nanomaterials compared to unmodified ZnO nanomaterials. The nanocomposite of ZnO exhibits highest photocatalytic and antibacterial activity among all nanomaterial. The degradation of the dyes depends on both its concentration as well as the amount of photocatalyst.
