Abstract
The use of nanosized semiconductor particles in various forms for the photocatalytic degradation of pollutants has been discussed. The aim of this review is to provide a critical analysis of various reports on the degradation of pollutants by various semiconductor nanomaterials. It has been shown that self-organized one-dimensional nanotube matrix creates a better opportunity to remove pollutants more efficiently than the randomly oriented nanoparticles. The use of metal doping and mixed semiconductor systems has also been analyzed. Although large improvements in the present technology are required, the review points to focus on the advantages of nanomaterials compared to bulk materials in efficient purification of water.
