Hydrogen production aided by new (1-x) SrTi0.5Fe0.5O3-delta-xCe(0.8)(Sm0.8Sr0.2)(0.2)O2-delta(MIEC) composite membranes
(2014)
In the present work, composite materials of the type (1-x)SrTi0.5Fe0.5O3-delta-xCe(0.8)(Sm0.8Sr0.2)(0.2)O2-delta (with x = 0, 0.25, 0.5, 0.75 and 1) are obtained by the two step solid state technique. Their transport ...
Efficient and poison-tolerant PdxAuy/C binary electrocatalysts for glucose electrooxidation in alkaline medium
(2014)
Carbon supported PdxAuy binary catalysts for glucose electrooxidation and detection were prepared by a modified pulse microwave assisted polyol method. The physico-chemical properties were obtained by X-ray diffraction ...
Cu and Gd co-doped BaCeO3 proton conductors: Experimental vs SEM image algorithmic-segmentation results
(2014)
Segmentation algorithms for the quantitative description of the surface microstructure and the evaluation of the grain-boundary conductivity of ceramic materials surface using SEM microphotographs analysis was developed ...
Ordered mesoporous tungsten carbide/carbon composites promoted Pt catalyst with high activity and stability for methanol electrooxidation
(2014)
The current anode materials used for direct methanol fuel cells (DMFCs) are expensive and not sufficiently durable for commercial development. One of the major challenges lies in the development of an inexpensive, efficient ...
Carbon-supported PdSn and Pd3Sn2 anodes for glucose electrooxidation in alkaline media
(2014)
PdSn (20 wt.%) and Pd3Sn2 (20 wt.%) nanoparticles supported on Vulcan XC-72 carbon powders are prepared by a modified microwave-assisted polyol method and studied for the reaction of glucose electrooxidation in alkaline ...
Glucose electrooxidation over PdxRh/C electrocatalysts in alkaline medium
(2014)
Carbon Vulcan XC-72R supported PdxRh (x = 1, 2, 3) nanoparticles have been prepared by a modified pulse microwave assisted polyol method and have been studied for glucose electrooxidation in alkaline media. The PdxRh/C ...
Structural, thermomechanical and electrical properties of new (1-x) Ce0.8Nd0.2O2-delta-xBaCe(0.8)Nd(0.2)O(3-delta) composites
(2014)
In this work composite (1-x)Ce0.8Nd0.2O2-delta-xBaCe(0.8)Nd(0.2)O(3-delta) ceramics were prepared via the one-step citrate-nitrate combustion procedure, and characterised by TG-DSC, XRD analysis, and SEM. Their transport ...
Dimethyl phthalate degradation at novel and efficient electro-Fenton cathode
(2014)
A novel three-dimensional porous carbon nanotube sponge (CNTS) with high electrical conductivity was prepared, characterized and investigated as the catalytic cathode for oxygen reduction and employed for an electro-Fenton ...
Conductivity of Gd-doped BaCeO3 protonic conductor in H-2-H2O-O-2 atmospheres
(2014)
In the present investigation, a radically new and simple method of evaluation of the proton conductivity is proposed. This method is based on the conductivity measurement of ceramic materials depending on the oxygen partial ...
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 ...
