Preparation and properties of Sb-doped SnO2/metal substrates by sol-gel and dip coating

Antimony-doped SnO2 on a metallic substrate is a useful electrode for electrochemical water treatment. Sb-doped SnO2 films on aluminium and stainless steel were prepared by the sol-gel technique and dip coating method. The precursor metal alkoxide/alcohol solutions were derived from SnCl4 and SbCl3....

Zusammenfassung:	Antimony-doped SnO2 on a metallic substrate is a useful electrode for electrochemical water treatment. Sb-doped SnO2 films on aluminium and stainless steel were prepared by the sol-gel technique and dip coating method. The precursor metal alkoxide/alcohol solutions were derived from SnCl4 and SbCl3. Ammonia/alcohol solution was used for the synthesis and Cl- was eliminated by the precipitation of NH4Cl. The XRD pattern of the SnO2 film annealed at 400 C could be assigned to SnO2. The Sb-SnO2 film consisted of fine particles from 10 to 20 nm. In the electrolysis, Sb-SnO2/stainless steel electrodes showed an exfoliation but Sb-SnO2/aluminium did not. The results indicated that SnO2/Al can be promising as a SnO2 electrode for electrochemical water treatment. 21 refs.
