    Abstract

    Lanthanide perovskite oxides are mentioned as material for hydrogen peroxide sensor because they can catalytically decompose hydrogen peroxide in an aqueous medium. The catalytic properties of these perovskite oxides to hydrogen peroxide are suggested due to their oxygen vacancies influenced by the oxide non-stoichiometry. In this paper, we investigate the catalytic hydrogen peroxide decomposition of a La1-xSrxCoO3-δ thin film with x = 0.7 for sensing application. The oxygen vacancy concentration in the oxide is estimated via the work function measurement using an electrolyte metal oxide semiconductor field effect transistor (EMOSFET) with a platinum remote gate. The experimental results show the catalytic properties of this oxide to hydrogen peroxide increases with increasing its non-stoichiometry, x.
