Advancements in Metal Oxide/Polymer Nanocomposite Utilized as Photocatalysts for Wastewater Remediation

The fast industrialization and urbanization generate huge number of pollutants. Organic dyes (so called organic pollutants) play an important role in polluting water and contaminating the aquatic system. These dyes are mutagenic, carcinogenic and exhibit toxicity for aquatic eco-system and human health. Recently, advanced oxidation method has been adopted for the remediation of organic pollutant through oxidation by reactive oxidative species (ROS) in-situ generated by photocatalytic materials. To shed light towards photocatalysts, this chapter comprises the recent advancement on the synthesis of metal oxide/polymer nanocomposite materials and their utilization for the remediation of wastewater. Furthermore, detailed properties of metal oxides viz., titanium oxide (TiO2), zinc oxide (ZnO), tin oxide (SnO2), iron oxide (Fe3O4) and nickel oxide (NiO) and composites based on polymer materials have been discussed. Finally, it covers outlook of current challenges and achievements for the preparation of composite materials and their future aspects.
