Abstract

La1−xSrxCoO3−δ belongs to the group of perovskite oxides of the ABO3 structure, with a trivalent rare earth in the A position (La) and a trivalent metal ion in the B position (Co). Doping with divalent Sr-ions at the trivalent La-positions creates oxygen vacancies which give the oxide catalytic properties to H2O2. However, the conventional techniques which are used to prepare this oxide such as chemical methods are not suitable for making a thin film. In this paper, a thin layer of La1−xSrxCoO3−δ (x=0.5) perovskite oxide is deposited on a Pt electrode by using the pulsed laser deposition (PLD) technique. The catalytic properties of this perovskite oxide to hydrogen peroxide due to the presence of the oxygen vacancies will be discussed. The results show the possibility to use this perovskite oxide as a sensing material for potentiometric hydrogen peroxide sensors.
