Graphene Oxide Nanocomposites as a Promising Photocatalyst in the Degradation of Organic Dyes

Abstract

Globally, water pollution is a crucial environmental issue. Research has indicated the presence of chemicals in the aquatic environment, which includes dyes, antibiotics, and insecticides. Presently, there are numerous techniques available for the degradation of dyes which include physicochemical, chemical, biological, electrochemical, and membrane technologies along with sustainable techniques such as photocatalysis. The remarkable photocatalytic activity of graphene oxide nanocomposites is one of its most notable features. Graphene oxide's photocatalytic ability outperforms many traditional techniques, offering a quick and efficient way to remove dye. The detailed mechanism of graphene induced materials in the degradation of organic dyes was highlighted in the present study. Also, the current integration of graphene with plant sources and their usage as the photocatalysts are discussed. The present study could provide a nominal insight on the current trends in graphene-based bioremediation techniques and its efficacy as a pollutant removal system.
