Atomic Scale Insight Into High Voltage Degradation Mechanism in YSZ Electrolyte for Solid Oxide Electrolyzer Applications

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The evolution of yttria‐stabilized zirconia (YSZ) electrolyte microstructure after testing at progressively high voltages was captured at the micro‐ and atomic‐scale levels to determine the operational boundaries of a solid oxide electrolysis cell (SOEC).

Characteristics and Sinterability of Ceria Stabilized Zirconia Nanoparticles Prepared by Chemical Methods

Medžiagotyra, 2018
Microwave assisted and molten salts synthesis were extended for preparation of ceria (10 mol%; 15 mol%) stabilized zirconia and their parameters and sinterability were compared with that of particles prepared by the sol-gel combustion method. As-prepared

Rational design of Ni‐based catalysts for methane dry reforming: Recent advances and future perspectives

FlexMat, EarlyView.
Addressing the challenges inherent in dry reforming of methane (DRM), this paper focuses on the structural design and performance optimization of Ni‐based catalysts. The modulation strategies for DRM are systematically reviewed across four dimensions: the micromorphology of active metals, metal‐support interactions, electronic modifications by ...

Fabrication of BaZr0.1Ce0.7Y0.1Yb0.1O3‐δ Skeleton Structure for the Development of High‐Performance Nanocomposite Cathodes for Protonic Ceramic Fuel Cells by Nitrate Impregnation

Small, EarlyView.
A homologous BZCYYb1711 cathode skeleton was constructed using the same material as the electrolyte, and active components were introduced into the skeleton via nitrate impregnation to form a nanocomposite cathode. This strategy effectively alleviated the thermal expansion coefficient (TEC) mismatches between the cathode and electrolyte.

Cerium reduction at the interface between ceria and yttria-stabilised zirconia and implications for interfacial oxygen non-stoichiometry

APL Materials, 2014
Epitaxial CeO2 films with different thickness were grown on Y2O3 stabilised Zirconia substrates. Reduction of cerium ions at the interface between CeO2 films and yttria stabilised zirconia substrates is demonstrated using aberration-corrected scanning ...

Quasi‐In Situ 4D‐STEM Mapping of Exsolution Driven Parent Matrix Restructuring in Sr2FeMoO6‐δ

Small Methods, EarlyView.
How does catalytic exsolution alter its parent matrix in realistic solid oxide cells? A beam‐artifact‐free, quasi‐in situ 4D‐STEM methodology maps intrinsic nanoscale transformations in bulk Sr2FeMoO6‐δ electrodes. Correlative identical‐location imaging reveals that surface exsolution inherently couples with profound crystallographic reorganization and
