Characterization of Nickel-Antimony Doped Tin Oxide Electrodes Prepared via Sol-Gel Dip-Coating Method

Article Preview

Abstract:

Nickel and antimony doped tin oxide (NATO) electrodes were prepared by sol-gel dip-coating method. The effect of doping levels was investigated via scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS) and X-ray diffraction (XRD). The electrochemical ozone generation efficiency was also tested. The results showed that sol-gel prepared electrodes had a smoother surface morphology and lower current efficiency for ozone generation than electrodes prepared by traditional pyrolysis method. The nickel and antimony doping lead to a decrease in the crystallites size, while its effects on ozone generation efficiency were complex.
