Abstract

Cu₂O/TiO₂ nanotube heterojunction arrays have been prepared by photoreduction depositing Cu₂O nanoparticles on TiO ₂ nanotube arrays. The heterojunction arrays show uniformly distributed Cu₂O nanoparticles, and high crystallinity of anatase and cubic from the TiO₂ and Cu₂O, respectively. The asymmetry of the current-voltage plot for the material reveals that a heterojunction has been formed between TiO₂ and Cu₂O. Enhanced charge separation efficiency and improved photoconversion capability are confirmed by electrochemical impedance spectroscopy and photocurrent measurement. © 2009 American Institute of Physics.
