Application of magnetic nano-photocatalysts in water treatment processes

Water is the most widely used material in the world. Aquatic life and drinking water supply can be considered as the most important challenges which the globe is facing. There are many ways of water resources conservation. Among them, degradation of pollutant by magnetic nano photocatalysts has been proposed as one of the most interesting methods used in the field of water and wastewater treatment. These catalysts using a magnetite core will be separated after the process and could be easily activated under the visible light radiation and can be used especially for organic pollutants degradation. In this paper, common magnetic nano-photocatalysts used for water purification and environmental protection have been studied.
