Water Treatment by Photocatalysis

Water Treatment by Photocatalysis

Treatment of wastewater containing persistent organic and inorganic pollutants, prior to disposal into the environment, has attracted substantial interest over the past decades. Phenolic and Cr (VI) contaminants are carcinogenic in nature and pose a threat to both aquatic and human life.

The generation of secondary waste, high capital cost and low performance of conventional methods made photocatalysis a considerable option. The project targets purification of wastewater by solar energy, which includes two reactions, oxidation of organic pollutants to CO2 + H2O and reduction of Cr (VI) to less toxic form Cr (III).

The project will focus on fabrication of low cost, non toxic and highly efficient photocatalysts and their application in wastewater treatment. The relevant reaction mechanism will also be investigated by spectroscopies and other advanced technologies, which will be fed back to the material synthesis to improve the catalytic efficiency.
