BaCeO3: Materials development, properties and application
(2014)The characteristic of a number of oxide materials, which include BaCeO3-systems, is their ability to show the proton conductivity along with oxygen-ion conductivity. Such atypical behavior for other oxides attracts great ... -
Electrochemically promoted catalysis: The case of ethanol oxidation over Pt
(2002)Ethanol oxidation was investigated over polycrystalline Pt films deposited on 8 mol% Y2O3-stabilized-ZrO2 (YSZ) in the temperature range of 300-350degreesC. It was found that electrochemical supply of oxygen anions (O2-) ... -
Influence of Cu on the properties of gadolinium-doped barium cerate
(2008)In the present work the effect of copper oxide addition on the densification behavior and electrical conductivity of BaCe1-xGdxO3-delta (BCG) type ceramics is investigated. Small addition (1 mol%) of this sintering additive ... -
Insights on thermal and transport features of BaCe0.8-xZrxY0.2O3-delta proton-conducting materials
(2015)BaCe0.8-xZrxY0.2O3-delta-based materials (BCZYx, 0 <= x <= 0.8) are obtained through a modified citrate-nitrate combustion method at 1150 degrees C with following sintering at 1450 degrees C. Then their thermomechanical ... -
Investigation of a Ba0.5Sr0.5Co0.8Fe0.2O3-delta based cathode SOFCII. The effect of CO2 on the chemical stability
(2007)The effect of carbon dioxide on the chemical stability of a Ba0.5Sr0.5Co0.8Fe0.2O3-delta cathode in the real reaction environment at 450 degrees C was investigated by X-ray photoelectron spectroscopy (XPS), scanning electron ... -
Investigation of the structural and electrical properties of Co-doped BaCe0.9Gd0.1O3-delta
(2011)In the present work the effect of cobalt oxide addition on the density and on the electrical properties of gadolinium-doped barium cerate is investigated. A series of BaCe0.9-xGd0.1CoxO3-delta (x = 0.00, 0.01, 0.03, 0.05, ... -
Sulfur and carbon tolerance of BaCeO3-BaZrO3 proton-conducting materials
(2015)In the present work, BaCe0.8-xZrxY0.2O3-delta-based ceramic samples (BCZYx) are prepared and their chemical stability in corrosive atmospheres containing high concentrations of H2O, CO2 and H2S is investigated. Based on ...
