Fabrication of Cu2O/TiO2 nanotube heterojunction arrays and investigation of its photoelectrochemical behavior
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.
