Hydrogen production aided by new (1-x) SrTi0.5Fe0.5O3-delta-xCe(0.8)(Sm0.8Sr0.2)(0.2)O2-delta(MIEC) composite membranes

Murashkina, A.; Pikalova, E.; Medvedev, D.; Demin, A.; Tsiakaras, P. (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 ...

Structural, thermomechanical and electrical properties of new (1-x) Ce0.8Nd0.2O2-delta-xBaCe(0.8)Nd(0.2)O(3-delta) composites

Medvedev, D.; Pikalova, E.; Demin, A.; Podias, A.; Korzun, I.; Antonov, B.; Tsiakaras, P. (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 ...

Novel composite solid state electrolytes on the base of BaCeO3 and CeO2 for intermediate temperature electrochemical devices

Medvedev, D.; Maragou, V.; Pikalova, E.; Demin, A.; Tsiakaras, P. (2013)

In the present work, nano-sized powders of (1-x)Ce0.8Sm0.2O2-delta-xBaCe(0.8)Sm(0.2)O(3-delta) (x = 0, 0.3, 0.5, 0.7 and 1) were obtained by solution combustion synthesis (self-combustion synthesis, SCS) method of nitrate ...

BaCeO3: Materials development, properties and application

Medvedev, D.; Murashkina, A.; Pikalova, E.; Demin, A.; Podias, A.; Tsiakaras, P. (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 ...
