NOVELTY - Preparation of graphene-titania fiber comprises ultrasonically dispersing 0.15-0.20 g graphene and tetrahydrofuran, adding ethyl acetoacetate as chelating agent and tetrabutyl titanate, mixing, heating at 82 degrees C to reflux for 1 hour, adding deionized water, stirring, heating at 70 degrees C to reflux for 1 hour, carrying out rotary evaporation until viscosity is 5-75 Pa-second, maintaining temperature at 25-450 degrees C under nitrogen atmosphere, and cooling. USE - Method for preparing graphene-titania fiber (claimed) used for wastewater treatment. ADVANTAGE - The fiber has excellent photocatalytic property.
