Title: Physicochemical properties of SnO{sub 2}-Sb{sub 2}O{sub 5} films prepared by the spray pyrolysis technique

Abstract

Tin dioxide films doped with Sb(V) of F{sup {minus}} have interesting electrochemical properties in different electrode processes, like low temperature electrochemical combustion of organic pollutants, ozone production, and organic electrosynthesis. The properties of SnO{sub 2}-Sb{sub 2}O{sub 5} mixed-oxide films prepared by the spray pyrolysis method were studied under different synthesis conditions. The film density, measured by profilometry and by a spectrophotometric method, was close to that reported in the literature for crystalline tin dioxide. Analysis by energy dispersive spectrometry and X-ray photoelectron spectroscopy showed that the Sb/Sn atom ratio int eh films was in all cases about 2.5 times larger with respect to that in the precursor solution. Microstructural characterization by wide-angle X-ray scattering indicates that the deposits consist of large sized crystallites. The influence of the substrate temperature (T) on the average crystallite size (l) has shown that l decreases linearly with T. Scanning electron microscopy showed that the surface of films thinner than 0.5--0.8 {micro}m is flat with only a limited number of emerging particles.
