Electrochemical Degradation of Methyl Orange by Samarium and Antimony Codoped SnO₂ Electrodes

Abstract:

In this work, samarium and antimony (Sm–Sb) codoped tin oxide (SnO₂) films have been successfully prepared on titanium (Ti) substrate by a facile sol gel method. The samples were characterized by X–ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). The composite film materials were used as anode for the electro-degradation of methyl orange solution. Two effective factors of electro–catalytic properties namely, the content of Sm in the SnO₂ samples and the calcination temperature, have been optimized based on the electro-degradation experiments. A moderately calcination temperature of 873 K and 1.0% Sm doping owned the best performance. The smaller grain sizes and optical band gap of the SnO₂ by introduction of the Sm improved electro-catalytic activity.
