SYNTHESIS OF MATERIALS FOR DISCOLOURATION AND DEGRADATION OF ORGANIC POLLUTANTS IN WATER: GRAPHENE ALONE AND GRAPHENE NANOCOMPOSITE (GRAPHENE-TITANIUM DIOXIDE)

摘要

The invention relates to a method for treating water containing organic pollutants (dyes and pesticides), in particular with a view to reusing said water for irrigation, in industry or even as drinking water. This method is also applicable to the treatment of industrial effluents rich in organic impurities. The developed method relates to the use of photo-catalysts based on nanostructured carbon and a nanosized metal oxide. The scientific and technological obstacles of this method actually lie in the preparation of nanocomposites based on graphite and functionalised graphene (graphite oxide, graphene, graphene-titanium dioxide nanocomposite (GF@TiO2)) capable of degrading organic pollutants in water in the absence of ultra-violet (UV) radiation, and the production methods and uses thereof.
