(In-press) State of the Art Review of Photocatalytic Water Treatment
Keywords:Photocatalysis, Water Treatment, Metal Oxides, Metal organic frameworks, Carbon Materials, Nanocellulose
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 clean water demand and availability is expected to worsen. The use of emergent organic contaminants (EOCs) and inorganic pollutants constitute a significant threat to human health and the environment. The most promising approach for water treatment is the use 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 degradation of pollutants from water. This review article provides an overview of photocatalytic water treatment technology, discussing the basic mechanism of photocatalysis and nanobased photocatalysts used for the degradation of organic pollutants in water and wastewater.
