Abstract
Visible light driven tin oxide based photoelectrodes were obtained using SnCl2·2H2O EtOH solution on FTO by dip** and with further heat treatment in air. Photoelectrochemical measurement with three electrodes configuration under visible light irradiation (γ>420 nm) revealed that this as-prepared photoelectrode showed typical n-type photocurrent effect and the onset potential is negative than that of H+/H2. XRD, UV-Vis spectrum and control experimental results revealed that the visible light driven mechanism for the tin oxide based photoanode maybe ascribed to Sn4+/Sn2+ transformation and the surface oxygen deficiency.
