“…Mixed ionic‐electronic conducting (MIEC) oxides are a kind of multi‐functional materials. It can be applied as high active cathodes for solid oxide fuel cells (SOFCs), as membranes for oxygen separation with infinite selectivity, as catalytic membrane reactors for selective oxidation or reduction reactions, integrated with oxy‐fuel process for CO 2 capture . Among these applications, MIEC materials as oxygen separation membranes producing high purity oxygen at elevated temperature is promising to be commercialized in the near future due to its low costs and high efficiency compared with pressure swing adsorption and cryogenic distillation technologies .…”

in Wiley Online Library (wileyonlinelibrary.com)Oxygen permeation through mixed ionic-electronic conducting membrane may be controlled by oxygen bulk diffusion and/ or oxygen interfacial exchange kinetics. In this article, we chose BaCe 0.05 Fe 0.95 O 3-d (BCF) as a representative to study the oxygen transport resistances of the membrane coated with different porous catalysts, including BCF itself, Ba 0.5 Sr 0.5 Co 0.8-Fe 0.2 O 3-d (BSCF) and Sm 0.5 Sr 0.5 CoO 3-d (SSC). The oxygen transport resistances of bulk, gas-solid interfaces of feed-side and sweep-side of the catalyst-coated membranes can be separately obtained through a linear regression of experimental data according to an oxygen permeation model. The three resistances of the membrane coated with BCF catalyst are smaller than those of the membrane coated with BSCF and SSC catalysts, although BSCF catalyst itself has the fastest bulk diffusion and interfacial exchange kinetics. The catalytic activities of BSCF and SSC catalysts on BCF membranes are impacted by the transport kinetics of catalysts, microstructure of catalyst layers, and cationic inter-diffusion between the membrane and catalysts.

“…This new study by Brenes and coworkers published in the inaugural issue of Joule has shown, for the first time, that thin film perovskites can be tailored to have key semiconductor material properties-including diffusion lengthscomparable to those of single crystal materials. 6 Perovskite materials are well known to be incredibly sensitive to both light and humidity. 7 Fully fabricated devices generally prefer exposure to as little of each as possible.…”

Hydrogen fuel is a kind of clean energy that can be generated by photo catalyzing water splitting. It is interesting to investigate the case contrasting to Gibbs free energy determination formula (GFEDF). Through calculation and theoretical analysis, results are: (1) there is not electric energy and other form of work consumed in photo catalyzing water splitting, hence, the work from outside environment is less than the change of Gibbs free energy; contracting to GFEDF. (2) GFEDF works with a reaction when absorbed heat is less than the heat for entropy change; GFEDF does not work with a reaction when absorbed heat is more than the heat for entropy change. Thereby, work is not always more than the change of Gibbs free energy to make a nonspontaneous reaction occur.
