What is it about?
Water is the most essential life form on earth and a prerequisite for human survival. Due to manifold anthropogenic and industrial activities, voluminous discharge of diverse organic and inorganic pollutants has blown up into the water bodies. The semiconducting nano-materials are highly beneficial for their application in the photocatalytic treatment of wastewater due to their favorable properties.

Why is it important?
Organic pollutants, in particular, have a major contribution to the degradation of water quality on a vast scale. There is an exigent need for the abatement of these organic contaminants from water and wastewater. Modified metal oxide-based photocatalysts have been discussed at length for the effective utilization of the visible spectrum of light for degradation of organic pollutants. Sunlight is a clean and abundant source, so this method is ecofriendly and offers minimal cost for effective treatment of environmental pollutants.
Perspectives
There are different types of materials and methods employed for waste water treatment. But photocatalysis method applies the solar light happens to be the clean and cost effective method. This chapter discusses the various nanomaterials specially metal oxides catalysts and their applications in degradation of organic and inorganic pollutants. These materials bear distinct morphological and structural properties which are employed in the photocatalytic process. Overall this article provides comprehensive information on the subject mater which will be useful to all the material scientists and environmental field researchers.
