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 ...

Toward Efficient and Reliable Chemical Upgrading Using Solid Oxide Electrochemical Reactors, Mechanisms, Challenges, and Design Principles

Small, EarlyView.
Solid oxide electrochemical reactors (SOERs) offer a compelling pathway for coupling renewable electricity with chemical manufacturing, but their real application is still limited by low efficiency and instability. This review systematically summarizes SOER reaction mechanisms, performance‐limiting factors, and recent progress toward high‐efficiency ...

Ion Beam Sputtering Deposition to Prepare Pt/ZrO2 Active Layer for Hydrogen Evolution and Oxidation Reaction

ChemElectroChem, Volume 13, Issue 9, 5 May 2026.
Pt@ZrO2 thin films are fabricated by ion beam sputtering as compact, binder‐free electrodes with low Pt loading (0.0475 mg·cm−2). The intimate mixing between the noble metal and the ceramic support enhances intrinsic catalytic activity toward alkaline hydrogen evolution, allowing a significant reduction in precious metal loading while maintaining ...

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 ...
