A composite photocatalyst based on graphene oxide and titanium dioxide has been developed and tested. The catalyst has been obtained as an aerogel, which consisted of granules (spheres and hemispheres) with a diameter of 4-6 mm. This form of catalyst has been proved more convenient for use in comparison with powder photocatalysts from a technological point of view. The resulting composites have shown high photocatalytic properties exemplified by photodegradation of the basic dyes methyl violet and methylene blue in aqueous solutions.
