Abstract
The increasing contamination of freshwater systems from a wide variety of industrial municipal and agricultural sources which are released deliberately into the environment has seriously affected water quality Although the nature of pollution problems may vary they are typically due to pesticides organic dyes and emerging contaminants EC Many of these chemical pollutants are able to pass through municipal wastewater treatment plants WWTP at least to some extentRecently research activities have been centered on advanced oxidation processes AOPs for the destruction of pollutants resistant to conventional methods As one of the important AOPs the heterogeneous photocatalytic oxidation process is of special interest especially when solar light is usedThis chapter presents a critical review of the achievements in photocatalytic semiconductors aimed at enhanced TiO2 photocatalytic efficiency complete mineralization of organic compounds efficient utilization of visible and/or solar light stability and reuse of semiconductor materials in real wastewater treatment
