Transition metal oxides are potential alternatives to noble catalysts for oxidation reactions. Co-based spinel oxides, in particular, have attracted significant attention. Herein, NixCo3–xO4 were synthesized elucidate the influence of oxygen vacancies on catalyst activities and reaction mechanisms ethane combustion. A correlation between activity population properties O defects was developed, with an increased number typically resulting higher activity. Also, shape-induced facet effect is...
Abstract Multicomponent oxides are intriguing materials in heterogeneous catalysis, and the interface between various components often plays an essential role oxidations. However, underlying principles of how hetero-interface affects catalytic process remain largely unexplored. Here we report a unique structure design MnCoO x catalysts by chemical reduction, specifically for ethane oxidation. Part Mn ions incorporates with Co to form spinel 3- O 4 , while rests stay as MnO 2 domains create...
In this study, adsorption and desorption of mixtures organic compounds commonly emitted from automotive painting operations were experimentally studied. A mixture two alkanes a eight adsorbed onto beaded activated carbon (BAC) then thermally desorbed under nitrogen. Following both regeneration, samples the BAC chemically extracted. Gas chromatography-mass spectrometry (GC-MS) was used to quantify in gas streams extracts. general, for adsorbate mixtures, competitive resulted displacing low...
Carbothermal hydrogen reduction (CHR) of ammonium heptamolybdate impregnated activated charcoal (AC) yields a mixed Mo2C/MoOxCy catalyst. As the CHR temperature increases (from 600 to 800 °C) Mo2C content increases. At 675 °C graphite networks are generated that attach β-Mo2C particles, and at ≥700 agglomeration sintering occur, all which decrease catalyst activity. An optimal ∼650 is identified based on activity for hydrodeoxygenation (HDO) 4-methylphenol (4-MP) 350 4.3 MPa H2 high...
Abstract Bowtie‐shaped NiCo 2 O 4 nanostructures are prepared using a hydrothermal method. Variation of the synthesis parameters, including reaction time, additives, and calcination temperature, allows an understanding origin bowtie‐shaped structure to be developed. Methane oxidation experiments performed temperature‐programed (TPO) show that new materials, which do not contain precious metals, have excellent activity for low‐temperature methane combustion, with 100% conversion at ≈410 °C...
Hydrogen, with its high energy content and environmental-friendly properties, is considered an effective carrier in addition to fossil fuels. Methane reforming represents a major method of hydrogen production, although the applied catalysts often suffer from coke deposition metal sintering at operating temperatures. Transition-metal carbides (TMCs), particularly molybdenum (MoxC), possess features such as Pt-like behaviors, affinity oxidants CO2 H2O, strong metal–support interaction for...
The hydrodeoxygenation (HDO) of 2-methoxyphenol (or guaiacol, GUA) over Pd, Ru, and Mo2C catalysts supported on activated carbon (AC) is compared. activities the for hydrogenation versus deoxygenation a per site basis, measured range temperatures in liquid phase batch reactor at high H2 pressure (3.4 MPa), are quantified using lumped kinetics. overall GUA consumption rate decreases order Pd > Ru Mo2C. Hydrogenation phenyl ring occurs low temperature (240 °C) both Pd/AC Ru/AC catalysts. At...

Abstract Transition metal carbides (TMCs) have emerged as highly intriguing materials for CO 2 hydrogenation, primarily due to their excellent ability on adsorption and activation, strong metal‐support interaction (SMSI), well the engineered metal/TMCs or TMCs/substrate interfaces fine‐tuning of activity selectivity. In this review, strategies modulating structure properties TMCs attain desirable products in hydrogenation are discussed from following perspectives: 1) Manipulation metal/C...
Silica-supported magnetic cobalt ferrite complex oxides, CoFe2O4/SiO2, with different loading of 5, 10, 20, and 50% were simply prepared by a sol–gel autocombustion method using colloidal aqueous silica solution as cheap source.
