“…Nevertheless, when doped with Ar, B, Bi, F, P, or Sb, its conductivity increases considerably [1][2][3][4][5][6]. There have also been attempts to use less common elements as doping agents, like Ir, Rh, and various lanthanides [7][8][9][10][11][12].…”

A Ti/SnO 2 -Sb 2 O 4 electrode was prepared by alternate Sn and Sb electrodepositions using the thermoelectrochemical method. The chemical, electrochemical, and structural characterization of the electrode was performed and it was tested in the anodic oxidation of several pollutants, phenol, ibuprofen, acid orange 7 (AO7), and diclofenac, all in aqueous 0.035 M Na 2 SO 4 solutions at current densities of 10 and 20 mA cm -2 . After the 24 h assay, removal of chemical oxygen demand, total organic carbon (TOC) and absorbance were very high, especially at the higher current density. TOC removals presented the lowest value. However, after 24 h at 20 mA cm -2 , TOC removals were: phenol-94%; ibuprofen-83%; AO7-88%; and diclofenac-73%. Combustion efficiency and instantaneous and mineralization current efficiencies were also determined.

“…This kind of oxide exhibits very high resistivity at room temperature and thus cannot be used as an electrode material directly. However, its conductivity can be improved significantly by doping Ar, B, Bi, F, P or Sb [9,[22][23][24][25][26][27]. Doped SnO 2 films are usually used as transparent electrodes in high-efficiency solar cells, gas detectors, far IR detectors and transparent heating elements [28].…”

Anodic oxidation is a promising process for degrading toxic and biologically refractory organic pollutants present in wastewater treatment. Proper selection of electrodes is the key to reach effective and economic operation. In this study, two types of electrodes, i.e. the recently developed Ti/BDD and Ti/SnO 2 -Sb 2 O 5 , which is generally believed to be superior to the conventional electrodes, were compared under the same conditions. It was found that the Ti/ BDD electrode could mineralize both phenol and reactive dyes effectively. But the Ti/SnO 2 -Sb 2 O 5 electrode could only mineralize phenol. When oxidizing more refractory reactive dyes, it demonstrated very poor activity. In addition, the Ti/BDD electrode had a service life of 264 h in an accelerated life test, but the Ti/SnO 2 -Sb 2 O 5 was irreversibly damaged within several seconds. The direct experimental comparison in the present study indicates that the Ti/BDD electrode is much better than the Ti/SnO 2 -Sb 2 O 5 electrode for pollutant oxidation.

“…The composition of the sample was calculated as O 2 -65.54 %, Sn-29.38 % and Cl-5.08 %. The variation of the atomic percentage of Sn and O 2 and presence of Cl contaminate as residue gave the film a nonstoichiometric nature due to which the film showed a higher conductivity without introducing any doping [4,13]. …”

Tin oxide (SnO 2 ) thin films have been grown on glass substrates using atmospheric pressure chemical vapour deposition (APCVD) method. During the deposition, the substrate temperature was kept at 400°C-500°C. The structural properties, surface morphology and chemical composition of the deposited film were studied by X-ray diffraction (XRD), scanning electron microscope (SEM) and Rutherford back scattering (RBS) spectrum. XRD pattern showed that the preferred orientation was (110) having tetragonal structure. The optical properties of the films were studied by measuring the transmittance, absorbance and reflectance spectra between O = 254 nm to 1400 nm and the optical constants were calculated. Typical SnO 2 film transmits ~ 94% of visible light. The electrical properties of the films were studied using four-probe method and Hall-voltage measurement experiment. The films showed room temperature conductivity in the range 1.08 × 10 2 to 1.69 × 10 2 : -1 cm -1 .
