NOVELTY - Preparation of graphene oxide quantum dots (GOQDs)/titanium dioxide (TiO2)/tungsten oxide (WO3) photocatalyst comprises taking 20-50 ml GOQDs solution, ultrasonically processing, adding sodium tungstate dihydrate (Na2WO4.2H2O), strongly stirring for 1 hour, completely dissolving, adding 80 ml absolute ethyl alcohol on a magnetic stirring apparatus, stirring while adding butyl titanate, adding 0.4 ml hydrofluoric acid (HF), stirring for 30 minutes, mixing the two solutions and stirring for 1-2 hours, transferring to 100 ml hydrothermal reaction kettle, conducting hydrothermal reaction, washing the obtained product with pure water and absolute ethyl alcohol until neutral and drying in a constant temperature drying box at 60 degrees C. USE - Preparation of GOQDs/TiO2/WO3 photocatalyst used for wastewater treatment (claimed) or sewage treatment. ADVANTAGE - The method provides GOQDs/TiO2/WO3 photocatalyst, which has improved TiO2 light quantum yield, expanded light absorption wavelength, high photocatalytic reaction activity, and widened photocatalytic sewage treatment, and provides a strong support for removing heavy metal endocrine disruptors in wastewater.
