The necessity of the thesis Currently environmental pollution is at an alarming level especially pollution of textile industry wastewater. Therefore the research and development of materials as well as the textile and dyeing wastewater treatment methods are essential requirements. The removal of harmful organic pollutants through advanced oxidation processes AOPs photocatalytic oxidation is attracting an increasing attention. Heterojunctions in photocatalysts has been proved to be one of the most promising ways for the preparation of advanced photocatalysts because of its feasibility and effectiveness for the spatial separation of electron hole pairs. 2.
