NOVELTY - Preparing photocatalyst comprises pre-treating 0.5 g of commercial P25-titanium dioxide at a temperature of 200-800 degrees C for 0.5-5 hours, dispersing the graphene oxide (0.0025 wt.%) in deionized water to uniform graphene oxide solution, dispersing the pre-treated titanium dioxide into 10 ml of graphene oxide solution and then uniformly stirring to obtain stable titanium dioxide-graphene oxide suspension, performing hydrothermal treatment at a temperature of 100-200 degrees C for 0.5-10 hours, and washing the obtained product for 3 times and then vacuum drying. USE - The method is useful for preparing photocatalyst. ADVANTAGE - The method allows simple preparation of the photocatalyst with high electronic mobility and efficiency in an environmentally friendly manner.
