We present a novel solid/liquid Co3O4-36 wt % Bi2O3 composite that can be used as molten oxide membrane, MOM ( Belousov, V. V. Electrical and Mass Transport Processes in Molten Oxide Membranes. Ionics 22 , 2016 , 451 - 469 ), for ultrahigh purity oxygen separation from air. This membrane material consists of Co3O4 solid grains and intergranular liquid channels (mainly molten Bi2O3). The solid grains conduct electrons, and the intergranular liquid channels predominantly conduct oxygen ions. The liquid channels also provide the membrane material gas tightness and ductility. This last property allows us to deal successfully with the problem of thermal incompatibility. Oxygen and nitrogen permeation fluxes, oxygen ion transport number, and conductivity of the composite were measured by the gas flow, volumetric measurements of the faradaic efficiency, and four-probe dc techniques, accordingly. The membrane material showed the highest oxygen selectivity jO2/jN2 > 10(5) and sufficient oxygen permeability 2.5 × 10(-8) mol cm(-1) s(-1) at 850 °C. In the range of membrane thicknesses 1.5-3.3 mm, the oxygen permeation rate was controlled by chemical diffusion. The ease of the MOM fabrication, combined with superior oxygen selectivity and competitive oxygen permeability, shows the promise of the membrane material for ultrahigh purity oxygen separation from air.

“…Other perovskites, which may also be used as oxygen-permeation membranes, were mentioned in a review written in 1997 by Bouwmeester and Burggraaf (The Netherlands) [370]. Much more recently, Belousov et al (Russia) [371] presented gas-tight ceramic composites consisting of ion-conducting δ -B 2 O 3 and electronically conducting metal oxides such as In 2 O 3 as ion transport membranes for oxygen separation from air.…”

Solid State Ionics has its roots essentially in Europe. First foundations were laid by Michael Faraday who discovered the solid electrolytes Ag2S and PbF2 and coined terms such as cation and anion, electrode and electrolyte. In the 19th and early 20th centuries, the main lines of development toward Solid State Ionics, pursued in Europe, concerned the linear laws of transport, structural analysis, disorder and entropy and the electrochemical storage and conversion of energy. Fundamental contributions were then made by Walther Nernst, who derived the Nernst equation and detected ionic conduction in heterovalently doped zirconia, which he utilized in his Nernst lamp. Another big step forward was the discovery of the extraordinary properties of alpha silver iodide in 1914. In the late 1920s and early 1930s, the concept of point defects was established by Yakov Il'ich Frenkel, Walter Schottky and Carl Wagner, including the development of point-defect thermodynamics by Schottky and Wagner. In terms of point defects, ionic (and electronic) transport in ionic crystals became easy to visualize. In an ‘evolving scheme of materials science’, point disorder precedes structural disorder, as displayed by the AgI-type solid electrolytes (and other ionic crystals), by ion-conducting glasses, polymer electrolytes and nano-composites. During the last few decades, much progress has been made in finding and investigating novel solid electrolytes and in using them for the preservation of our environment, in particular in advanced solid state battery systems, fuel cells and sensors. Since 1972, international conferences have been held in the field of Solid State Ionics, and the International Society for Solid State Ionics was founded at one of them, held at Garmisch-Partenkirchen, Germany, in 1987.

Oxygen plays a crucial role both in human life and in human economic activity and is the third (by volume) product in the world. Accelerated development of advanced energy technologies (solar photovoltaic and petrochemical industries) as well as biotechnology has stimulated the demand for ultra-high purity oxygen (above 99.999% purity). A newly developed copper and vanadium oxidebased two-layer mixed ionic electronic conducting -redox (MIEC-Redox) membrane with combined diffusion-bubbling oxygen mass transfer is of technological interest for ultra-high purity oxygen production as it demonstrates excellent oxygen selectivity and is easily made of affordable and inexpensive materials. Fundamental understanding of the formation, microstructure, and transport properties of MIEC-Redox membranes is important to be able to synthesize them in a controlled way and assess their potential for technological exploitation. The present article highlights the latest progress made in developing this understanding and outlines the further research directions. The ways to enhance the efficiency of oxygen separation through using these innovative diffusion-bubbling membranes are discussed. The proposed strategy of transition metal oxides-based thick membrane materials with fast combined diffusion-bubbling oxygen mass transfer opens up new vista for the design of next-generation energy materials with enhanced oxygen transport.
