Preparation of TiO2-Carbon Nanotube Composite Catalysts for Improvement of the Photocatalytic Activity of TiO2

摘要

TiO2 nanoparticles were deposited on carbon nanotubes (CNTs) for improvement of their photocatalytie activity. CNTs could be uniformly covered with TiO2 nanoparticles by the hydrolysis of titanium tetraisopropoxide in the presence of urea. Urea worked as linker molecules between the CNT surface and the TiO2 nanoparticles. The resultant TiO2-CNT composites showed a high catalytic activity for photodegradation of organic molecules.
