Metallic–Dissolution Triggered Defective NiCoAl‐CuO Electrocatalyst for Enhanced Ethanol Oxidation Reaction With Precisely Tuned Reaction Pathway

Carbon Energy, EarlyView.
Metallic dissolution triggers Al/O vacancies in NiCoAl–CuO, steering C2‐selective ethanol oxidation to acetate. Hybrid electrolysis co‐produces hydrogen and acetate with high efficiency and reduced cell voltage. ABSTRACT Replacing the sluggish anodic oxygen evolution reaction (OER) with value‐added processes like the ethanol oxidation reaction (EOR ...

Nanoscale inhomogeneities in melt-spun Ni-Al [PDF]

Le Journal de Physique IV, 2000
Abstract Ni x Al 100− x material with x =62.5 or 65 was rapidly quenched to room temperature by the melt-spinning technique and studied using X-ray diffraction, different transmission electron microscopy (TEM) modes and calorimetry measurements. Similar to bulk material, the initial B2 structure undergoes a martensitic transformation to the L1 0

Impact of Trace Water on the Macroscopic Activity of Commercial Ammonia Cracking Catalysts Under Process‐Relevant Conditions

Chemie Ingenieur Technik, EarlyView.
This study evaluates how small water impurities—typical in ammonia cracking feedstock—affect catalyst performance at elevated pressures and temperatures. By decoupling permanent degradation from reversible inhibition, the findings highlight trace water as a significant factor for reliable catalyst screening and industrial ammonia cracking scale‐up ...

Estimating the Internal Oxidation of Ni-Al Alloys [PDF]

Materials, 2019
Ni-Al alloys create a cone- shaped figure when there is internal oxide. This behavior was studied by TEM, SEM, X-Ray (XRD), Optical Microscopy and Image Processing. The internal oxide precipitates and its results indicate that this precipitation forms continuous rods in a cone-shaped configuration extending from the surface to the internal oxide front ...

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 ...
