Water Contamination by Organic-Pollutants: TiO2 Photocatalysis

  • Chapter
  • First Online:
Modern Age Environmental Problems and their Remediation

Abstract

Water sources are polluted continuously by a variety of organic compounds (PPCPs, Pesticides drugs, dyes). This contaminated water should be purified before using it. Among various techniques for the removal of these pollutants AOPs proved a promising technique in which redox reaction occurs that leads the formation of degraded products. Various nanomaterials have been used for this purpose. Titanium dioxide is used extensively. But, due to band large band gap energy it worked only in UV region that consume more energy. For making Titanium dioxide suitable in visible region, the doping of metal/non metal can be done. This chapter reveals mechanism of TiO2 as well the doped-TiO2 particle, changing of properties after doping and generation of new energy bands in the particles and also few combination of doped TiO2 in visible/UV region.
