Catalysts for the oxygen reduction reaction were prepared from pyrolysis of acetonitrile at 900 °C over iron particles on various supports. The phases present in active materials characterized by XRD, TEM, and Mössbauer spectroscopy. Typically, encased carbon after pyrolysis, explaining how they could survive subsequent acid washes. Fe included metallic gamma iron, cementite, two oxidized phases. Although relative abundance varied with different supports, treatment time, washing, there was...
The anaerobic oxidation of ethanol over spinel mixed oxides A2+Fe23+O42– (with A = Co2+, Ni2+, or Fe2+) was studied by means in situ diffuse reflectance spectroscopy (DRIFTS) and mass spectrometry (MS). nature the surface species formed during reaction its related gas products were discussed. Different pathways proposed depending on catalyst composition. Acetates appeared to be important intermediates case Ni ferrite which is at same time most basic easily reducible from set studied, whereas...
In this perspective, we present an overview of the most relevant advances in selective oxidation light paraffins to contribute petrochemical decarbonization processes. An analysis catalysts reported for methane chemicals focusing attention on oxidative coupling, dehydroaromatization, formaldehyde, and, more particularly, direct methanol is done. For ethane, examination centered investigated dehydrogenation ethylene, ammoxidation acetonitrile, and partial acetic acid. Finally, case propane,...
A series of iron-containing mesoporous silicas (Fe-HMS) with Fe contents up to 5.7 wt.% have been prepared at room temperature using the neutral hexadecylamine as surfactant molecule. Characterization these materials by a variety spectroscopic techniques, including EXAFS, EPR, Mössbauer and UV–Vis spectroscopies, suggests that species are tetrahedrally coordinated in as-made materials. Tetrahedra highly distorted two long short Fe–O bond distances due hydrogen-bonding type interactions...
This short review reports on spinel-type mixed oxides as catalysts for the transformation of biomass-derived building blocks into chemicals and fuel additives. After an overview various methods reported in literature synthesis with spinel structure, use this class materials chemical-loop reforming bioalcohols is reviewed detail. reaction aimed at production H2 intrinsic separation C-containing products, but also a very versatile tool investigating solid-state chemistry spinels.
In situ environmental STEM-(HA)ADF has been used to characterize a light alkane mild oxidation catalyst corresponding MoVTeO M1 phase. The results obtained show that there is almost no structure disordering under reaction conditions closed ethane oxidative dehydrogenation catalytic reactions: i.e., 350 °C 1 mbar of 30/15/55 O2/C2H6/N2 gas mixture. They further demonstrate {Te–Ox} chains present in the hexagonal channels participate redox process and constitute preferential pathway for...
