NOVELTY - Preparation of amine-functionalized graphene oxide/titania composite material, involves mixing hydrophilic fumed titanium dioxide and graphene oxide solution and then stirring to form stable suspension, transferring suspension to kettle and then performing hydrothermal reaction, reducing to obtain graphene-modified titania composite material, dispersing in solution containing ethanol and aniline, heating, washing, and drying. The mass ratio of aniline and graphene oxide is 1:1-80:1. USE - The method is useful for preparing amine-functionalized graphene oxide/titania composite material, which is useful for photocatalytic degradation of azo dyes. ADVANTAGE - The method is capable of easily preparing amine-functionalized graphene oxide/titania composite material with improved yield in an energy-efficient manner. DETAILED DESCRIPTION - Preparation of amine-functionalized graphene oxide/titania composite material, involves mixing 0.2 g hydrophilic fumed titanium dioxide and 0.2 mg/ml graphene oxide solution and then stirring to form stable suspension, transferring suspension to a kettle and then performing hydrothermal reaction at 100-200 degrees C for 1-15 hours, reducing to obtain graphene-modified titania composite material, soaking graphene-modified titania composite material in solution containing ethanol and aniline, heating mixture at 10-80 degrees C for 5-10 hours, washing with water and alcohol thrice, and drying at 30-120 degrees C. The mass ratio of aniline and graphene oxide is 1:1-80:1.
