A facile way to prepare visible light driven tin oxide based photoanode and its photoelectrochemical water splitting properties

Abstract

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