Method for obtaining photocatalysts based on titanium dioxide modified by reduced form of graphene oxide

摘要

the object of the application is a way to receive fotokatalizatorów, based on titanium dioxide reduced graphene oxide modified form using the method hydrotermalnej.the method is characterized by that,the titanium dioxide powder with reduced graphene oxide put form and treated hydrotermalnej in temperature 180°c autoclaved in the presence of 2-propanol.by 4 hours under pressure autogenicznego, followed by 1 hour at the same temperature under atmospheric pressure.the ratio of the mass of titanium dioxide to rgo is 1: 0.01 to 1: 0.1, and titanium dioxide to 2-propanol is 1: 0.8.then the composite is subjected to heat treatment in an inert gas atmosphere at a temperature of 300 - 700°c for 4 hours.advantageously applies industrial titanium dioxide anatase structure and specific surface area of 300 m2 / g and a particle size of 400 nm and a commercial rgo in the form of flakes.as the inert gas is argon, helium and nitrogen.
