Revealing the Giant Electromechanical Effects in Yttria-Stabilized Zirconia Single Crystal. [PDF]

Adv Sci (Weinh)
Giant electromechanical responses are uncovered in yttria‐stabilized zirconia single crystal (SC‐YSZ), exhibiting pronounced orientation dependence. The giant electrostriction and piezoelectricity are directly correlated with the long‐range transport kinetics of oxygen vacancies.

Iron-Based Catalysts on Tailored Alumina Supports for CO_x-Free Methane Decomposition to H₂ and Carbon. [PDF]

ChemistryOpen
Fe‐10ZrAl catalyst enables catalytic methane decomposition into COx‐free H2 and solid carbon. ZrO2‐modified alumina improves Fe particle stabilization, reducibility, and carbon growth behavior, giving the best performance among the tested catalysts with 76.5% CH4 conversion and 74.1% H2 yield at 800 °C.

Tuning Amorphous-Crystalline Catalytic Interfaces by Mechanochemistry: Cu-Based Metallic Glasses Coupled with Ceria for CO Oxidation. [PDF]

Adv Mater
Ball‐milling Cu‐based metallic glasses with ceria creates a unique nanostructure where metallic glass particles are wrapped by CeO2 nanoparticles. The intimate integration triggers copper state reorganization during reaction and aging, boosting CO oxidation and COPrOx activity.

Hydrothermal and Solvothermal Synthesis of Cerium-Zirconium Oxides for Catalyst Applications

International Journal of Technology, 2019
Cerium oxide (CeO2) is a rare earth metal oxide that has high oxygen storage capacity at low temperature. In order to enhance this capacity, as well as its thermal stability, it is necessary to combine CeO2 with zirconium oxide (ZrO2).
