Photoelectrochemical Performance of Nanostructured TiO2/CTCMT Composite Film Electrode

Abstract

Abstract: The photon-current conversion properties of nanostructured TiO₂/CTCMT composite film electrode were studied by using the photocurrent action spectra and the photocurrent dependence of potential. The bandgap of CTCMT film is 2.36 eV. The diagram of energy level of CTCMT film was determined with cyclic voltamogram and photoelectrochemical method. The valence band of CTCMT film is -5.52 eV, the conduction band is -3.16 eV, the p-n heterojuction exists in the nanostructured TiO₂/CTCMT film electrode, which favors the separation of electron/hole pairs generated by photoexcitation. The nanostructured TiO₂/CTCMT film electrode can enlarge the visible optical absorption region and obviously increase the photocurrent. The photocurrent threshold shifts to more than 600 nm, thus the photoelectric conversion efficiency is improved.
