Effect of Metal Dopant on the Performance of Ni@CeMeO₂ Embedded Catalysts (Me = Gd, Sm and Zr) for Dry Reforming of Methane

Methane, 2022
Biogas upgrading by a catalytic process has been studied in order to obtain syngas using renewable source of methane. This work evaluates the influence of metal dopant (Gd, Sm, and Zr) on the CeO2 structure for the dry reforming of methane over Ni ...

Electrochemical Memristive Devices Toward Brain‐Inspired Computing and In‐Memory Communication: Mechanisms, Materials, and Device Engineering

ChemElectroChem, Volume 13, Issue 9, 5 May 2026.
Electrochemical memristive devices, whose resistance is modulated by ion migration and redox reactions, offer a hardware pathway toward brain‐inspired computing. This review summarizes key switching mechanisms—electrochemical metallization (ECM), valence change mechanism (VCM), and thermochemical effects (TCM)—and discusses how materials and device ...

Improved Dry‐Pressing Strategy for Fabricating Double‐Sided Rough YSZ Electrolyte Thin Films and Their Performance in Solid Oxide Cells

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 3, May/June 2026.
ABSTRACT This study addresses limitations of the conventional dry‐pressing method for electrolyte‐supported films—smooth surfaces, excessive thickness, and fragile supports inducing damage. We propose an innovative camphor–quartz sand composite architecture to construct a five‐layer (camphor/quartz sand/YSZ/quartz sand/camphor) system, enabling thin ...

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

Ceria‐Zirconia Supported Gold Nanoparticles for CO and Soot Oxidation

ChemCatChem, Volume 18, Issue 9, 14 May 2026.
ABSTRACT This study introduces a gold nanoparticles catalyst (AuNPs) supported on ceria‐zirconia oxide, prepared by deposition‐precipitation (Au/CZ‐dep) and chemical reduction (Au/CZ‐red). The as‐prepared catalysts were tested in CO oxidation by O2 and soot oxidation under different oxidizing atmospheres (O2, NO2+NO+O2).
