Advances in Photo-catalytic Materials for Environmental Applications

Abstract

The growth of industry worldwide has extremely increased the generation and accumulation of waste by products. This has caused severe environmental problems that have become a major concern. Because of this, photo-catalytic pollutant degradation provided great opportunities and challenges in the field of environmental science. TiO2 nanoparticles have been extensively investigated for photo-catalytic decomposition of organic compounds. TiO2 is considered close to an ideal semiconductor for photo-catalysis but possesses certain limitations such as poor absorption of visible radiation and rapid recombination of photo generated electron/hole pairs. In this review article, various methods used to enhance the photo-catalytic characteristics of TiO2 including self-doping TiO2, doping TiO2 with metal and non-metal. Improving catalytic efficiency and exploring the reaction mechanism of photo-catalytic degradation of dyes as a model organic compound.
