Degradation of Orange G, Methyl Orange and Methylene Blue using Different Photocatalytic Systems

Abstract

Photocatalytic studies emphasize upon the chemical reactions that occur when light and a photocatalyst are present in a chemical reaction. A semiconductor known as a photocatalyst increases the rate of reaction just by being there. Numerous uses for photocatalysis exist, including water purification, self-cleaning, antimicrobial, de-odorizing, air purifying and antifogging. Since photocatalysis is a green chemical route, it is essential in the present times and is the need of the hour. Various industries are using different types of dyes in their routine processes including textile and leather industries. These industries put out a huge amount of dyes in their wastewaters which can be harmful to the human health. This short review emphasizes the application of different photocatalytic systems to degrade the dyes including Orange G, Methyl Orange and Methylene Blue which may be present in the industrial watsewaters.
