High-Efficiency CO₂ Electrolysis Enabled by Interface-Engineered Composite Electrolytes in Ni-Based SOEC. [PDF]

Adv Sci (Weinh)
This study addresses the critical issue of delamination between YSZ and GDC electrolytes in SOECs, which is caused by Thermal deformation disparity. A novel YSZ‐GDC composite interlayer, fabricated using a simple dip‐coating method, is introduced to solve this problem. This layer effectively suppresses delamination by mitigating thermal stress.

LiCo Dual-Doped Ceria-Based Composite as a Promising Low-Temperature Electrolyte for Metal-Supported Solid Oxide Electrolyzers. [PDF]

ChemSusChem
Enhanced sinterability and ionic conductivity are achieved with Li and Co dual‐doped GDC electrolytes for metal‐supported solid oxide electrolyzers. The optimized sample shows 2.17 × 102 S cm1 at 750 °C, which typically approaches the superionic solid electrolyte conductivity ranges. A tubular cell fabrication and analysis demonstrated its potential as

Tuning Amorphous‐Crystalline Catalytic Interfaces by Mechanochemistry: Cu‐Based Metallic Glasses Coupled with Ceria for CO Oxidation

Advanced Materials, EarlyView.
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.

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, EarlyView.
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 ...

Alloying Cu, Fe, and Co in Ni/YSZ Electrodes for High‐Temperature CO2 Electrolysis: Impact on TPB Density, Activity, and Carbon Deposition Resistance

Carbon Energy, EarlyView.
Systematic alloying of Ni with Cu, Fe, and Co in Ni/YSZ electrodes modifies active site density up to 43%, decreases activation energies by up to 44%, and reduces carbon deposition fourfold. Cu–Ni alloy is among the most promising alloy catalysts for electrochemical CO2 reduction in SOECs.

Design of High‐Performance MnCo1.5Cu0.5O4 Spinel Contact Material with Optimized Electrical Conductivity and Thermal Stability for Solid Oxide Electrolysis Cells by Cu Doping

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Cu‐doped spinel MnCo1.5Cu0.5O4 exhibits excellent conductivity and stability as SOC contact material. After 1000‐h aging at 850 °C, the contact layer maintains a 10 mΩ cm2 ASR value, and a single‐cell stack achieves a H2O/CO2 co‐electrolysis power density of 0.52 W cm−2.

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).

Hole Polaronic Confinement in (111) Yttria‐Stabilised Zirconia

Small, EarlyView.
Ultrathin epitaxial YSZ(111) films unexpectedly develop p‐type mixed conduction and amplified electromechanical coupling under oxidizing conditions. Combined transport measurements and first‐principles modeling reveal that nanoscale confinement and ordered dopant–vacancy complexes stabilize localized O 2p hole polarons at the surface. A canonical ionic

Transition of Ion Diffusion Mechanism in BaZr0.1Ce0.7Y0.1Yb0.1O3‐δ Electrolyte Under Real Operating Conditions

Small Methods, EarlyView.
Ion diffusion in the benchmark BZCYYb electrolyte is revealed to dynamically transition under realistic PCFC operating conditions. As temperature decreases, the electrolyte shifts from oxygen‐ion to proton‐dominant conduction via grain‐boundary hydrogenation and in situ hydration, even without external humidification.

Tuning Ce‐Zr‐Al Mixed Oxide Supports to Enhance Pt‐Pd Catalyst Performance for Low‐Temperature CO and C3H6 Oxidation in Diesel Emissions

ChemCatChem, Volume 18, Issue 5, 13 March 2026.
ABSTRACT Diesel oxidation catalysts (DOCs) with low‐temperature activity are required for low‐temperature combustion diesel (LTC‐D) engine technologies to meet emission regulations. To probe the impact of oxygen availability on activity, bimetallic Pt‐Pd catalysts supported on Ce‐Zr‐Al mixed oxides with varying Ce/Zr/Al contents were systematically ...
