Abstract
Realizing the importance of keeping our planet clean, researchers are actively working for eco-friendly alternative technologies for all areas of daily life. The presence of colored dye pollutants in water due to industrial, agricultural and domestic activities has led to the global need for the development of new and improved but efficient technologies to effectively address the challenges of water quality. Therefore it is necessary to develop technologies that could completely remove contaminants from contaminated waters. Semiconductor-mediated photocatalysis is a well-established technique for degradation of organic pollutants. TiO2 (titania) nanocatalysts have a proven potential to treat “difficult-to-remove” contaminants and thus are expected to play an important role in the remediation of environmental and pollution challenges. Doped-titania structures (nanoparticles, nanotubes, nanowires) are intended to be both supplementary and complementary to the present water-treatment technologies through the degradation of hazardous chemical wastes to innocuous end-products, that is, CO2 and H2O. This review article brings to attention the present scenario of water pollution, textile waste water, waste water treatment strategies, in particular, advancements of titania photocatalytic nanostructures in their use for water-treatment processes.
