state of the art review of photocatalytic water treatment

Supplying clean water is a major problem in contemporary societies. the rise of industrialization, urbanization, and population increases have caused a shortage of clean water supplies, and the disparity between healthy water demand and availability is expected to worsen. the use of emergent organic contaminants (eocs) and inorganic pollutants constitute a significant threat to the environment and human health.the most promising approach for water treatment is the usage of primary photocatalytic oxidation processes. the paper begins by outlining the issue of scarce water supplies and the many methods of purification, including photocatalysis using semiconductors like metal oxides, graphene oxides, and mofs. the article also reviews published research on the application of these photocatalysts materials for the reduction of pollutants from water. this review article provides an overview of technique for photocatalytic water treatment, discussing the basic mechanism of photocatalysis and nanobased photocatalysts utilized for the reduction of organic pollutants in water.
