Several antimony and platinum doped tin dioxide electrodes supported on titanium have been characterized by X-ray diffraction (XRD) and X-ray absorption spectroscopy (EXAFS) techniques. Ti/SnO2−Sb electrodes show a rutile-type nanostructure with a distorted unit-cell because of the substitution of the Sn(IV) ion by Sb(V). The presence of platinum on the electrode coating modifies the lattice parameters of the SnO2 cell due to an amorphization of tin oxide layers. The structural modifications on the different electrode after anodic polarization−deactivation have been analyzed.

Abstract

Several antimony and platinum doped tin dioxide electrodes supported on titanium have been characterized by X-ray diffraction (XRD) and X-ray absorption spectroscopy (EXAFS) techniques. Ti/SnO2−Sb electrodes show a rutile-type nanostructure with a distorted unit-cell because of the substitution of the Sn(IV) ion by Sb(V). The presence of platinum on the electrode coating modifies the lattice parameters of the SnO2 cell due to an amorphization of tin oxide layers. The structural modifications on the different electrode after anodic polarization−deactivation have been analyzed.
