▎ 摘　　要

NOVELTY - Producing nitrogen-doped titanium dioxide/graphene oxide complex, comprises (a) mixing graphene oxide and urea in polar solvent, (b) adding and mixing titanium precursor to the mixture, (c) hydrothermally synthesizing the mixture containing titanium precursor to prepare composite, and (d) heat treating the composite. USE - The method is useful for producing nitrogen-doped titanium dioxide/graphene oxide complex. ADVANTAGE - The complex has excellent pore structure and reduced band gap, and decomposes various organic substances.
