Abstract: In order to overcome the problem of low decomposition efficiency of organic pollutants from chemical nanocomposites by traditional decomposition methods, a rapid decomposition method of organic pollutants from chemical nanocomposites was proposed in this paper. The preparation process of chemical nanocomposite catalyst was determined, the experimental reagents and catalysts needed for the decomposition of organic pollutants were given, the cyclic decomposition experiment of organic pollutants in chemical nanocomposite was carried out, and the characterisation of materials after the decomposition of organic pollutants in chemical nanocomposite was analysed. Methylene blue solution was taken as the target organic pollutant to analyse the decomposition effect of organic pollutant without catalyst and with catalyst added. The experimental results show that both TiO₂-15RGo and TiO₂-30RGo have high photocatalytic degradation effect. RGO can catalyse the transfer effect of photo-generated electrons and improve the photocatalytic decomposition efficiency of organic pollutants in nanocomposites.
