Oxide/perovskite oxygen carriers

High-stability, high-capacity oxygen carriers iron oxide perovskite hybrid materials for hydrogen production by chemical looping. 3rd International Conference on Chemical Looping,... 

An important study of charge carrier in a typical ferroelectric perovskite-type oxide BaTiOa was published in 1964 by Glower and Heckman [10]. The title of the paper Conduction - Ionic or Electronic in BaTiOa was attractive for materials researchers in those days. In their paper, they reported about conduction species in barium titanate as follows Usual practice of authors has been to make the tacit assumption that conduction is exclusively electronic. There is no priori assurance that this is true. Also, they wrote In fact, to our knowledge, no one has to date addressed himself to the primary problem of transport, i.e., does conduction occur via the motion of electrons or of ions The purpose of their study was to answer this essential question from experimental results. They applied Cell [1] to BaTiOa specimens for different oxygen partial pressures Pi and P2-...
