Sorptive properties of antimony-doped In2O3

Inorganic Materials Aims and scope

Abstract

O2, Cl2, and SO2 chemisorption on the surface of nanocrystalline In2O3 doped with antimony (0.2 and 2.7 at %) has been studied at temperatures from 22 to 200°C. The results indicate that antimony prevents the formation of nonconducting indium chlorides on the surface of nanocrystalline In2O3 during Cl2 chemisorption. The logarithm of the conductivity of Sb-doped In2O3 is a nearly linear function of the surface coverage with chlorine, which makes it a candidate chlorine-sensing material. At the same time, antimony doping reduces the SO2 response of In2O3.
