Abstract

Cu2O/TiO2nanotube heterojunction arrays have been prepared by photoreduction depositing Cu2O nanoparticles on TiO2nanotube arrays. The heterojunction arrays show uniformly distributed Cu2O nanoparticles, and high crystallinity of anatase and cubic from the TiO2and Cu2O, respectively. The asymmetry of the current-voltage plot for the material reveals that a heterojunction has been formed between TiO2and Cu2O. Enhanced charge separation efficiency and improved photoconversion capability are confirmed by electrochemical impedance spectroscopy and photocurrent measurement.
