A uniformly distributed TiO2/CNTs composite film was fabricated by an in-situ chemical vapor deposition (CVD) method. CNTs are directly grown from the prepared TiO2 film by the spray pyrolysis deposition method doped with nickel oxide on Ni substrate. The nano-size TiO2 particles are uniformly distributed on the side walls of CNTs. The TiO2/CNTs composite exhibits high photocatalytic activity in the degradation of methyl orange (MO) and 95% of MO (10 mg/L) could be removed within 150 min under UV light irradiation. The results of the present study are promising for the development of a new method for the fabrication of well-distributed TiO2/CNTs composite film. (C) 2013 Elsevier B.V. All rights reserved.
