Great Diversity in Stability of Perovskite-Type Oxides Studied by Electrochemical Hydrogen Charging

【摘要】:Single crystals of 0.91Pb(Zn1/3Nb2/3)O3-0.09PbTiO3,SrTiO3 and BaTiO3,and ceramic pellets of CaCu3Ti4O12 and BiFeO3 have been studied and compared through electrochemical hydrogen charging,in which the oxides were coated with silver electrodes to electrolyze water as the cathode.Great diversity has been observed in the stability of the oxides:0.91Pb(Zn1/3Nb2/3)O3-0.09PbTiO3 was quickly decomposed;hydrogen could enter the lattice of the other four oxides,but their properties were influenced at extremely different speeds.Such a great diversity in stability against hydrogen among perovskite-type oxides highlights the importance of reliability study over functional oxides materials.
