Recent Progress in Intermediate Temperature SOFCs (ITSOFCs) Development at DLR [PDF]

, 2011
Metal-supported ITSOFCs having NiO or NiO+YDC 15 anode, yttria stabilized ceria electrolyte (YDC 15) and LSCF or LSCF+CGO composite cathodes were fabricated via plasma spraying for operation in the temperature range of 600-700°C.

Experimental methods in chemical engineering: Temperature‐programmed oxidation—TPO

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Temperature‐programmed oxidation (TPO) probes the oxidative capacity and redox properties of solid materials—catalysts, metal oxides, perovskites, and carbonaceous deposits. It identifies coke type, distribution, and reactivity. TPO instruments pass an oxidizing gas (diluted O2$$ {\mathrm{O}}_2 $$, air, or less commonly N2O$$ {\mathrm{N}}_2 ...

Ni–Pd Catalytic Synergy on Rod‐Shaped CeO2 for Boosting Low‐Temperature CH4 Oxidation

EcoEnergy, EarlyView.
Introducing Ni into Pd/CeO2 markedly accelerates deep CH4 oxidation by inducing a synergistic interaction between Ni and Pd species. This synergistic effect significantly improves low‐temperature activity and long‐term stability, providing a rational strategy for efficient CH4 abatement over Pd‐based catalysts under lean CH4 conditions while reducing ...

Origin of Physicochemical and Mechanical Stability of Low‐Temperature Prepared TiO2‐Based Photocatalytic Films: Surface Hydroxyl Density Matching

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Material science advances show how surface chemistry improves low‐temperature prepared TiO2‐SiO2 composite films. Using a colloidal‐based synthesis method instead of a powdered‐based one, researchers exploit hydroxyl groups' interfacial interactions to create nanoscale structures with superior physicochemical and mechanical stability.

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 ...

Preparation of Oxide Nanofibers for Analysis by Transmission Electron Microscopy

Microscopy Research and Technique, EarlyView.
Oxide nanofibers mounted on a MEMS chip for biasing. ABSTRACT The low electronic conductivity and rigid structure make sample preparation for in situ transmission electron microscopy (TEM) of oxide nanofibers challenging. This work evaluates three sample preparation approaches for mounting single oxide nanofibers on MEMS chips: (i) drop casting ...
