Electrochemical ammonia production on molybdenum nitride nanoclusters.
Theoretical investigations of electrochemical production of ammonia at ambient temperature and pressure on nitrogen covered molybdenum nanoparticles are presented. Density functional theory calculations are used in combination with the computational hydrogen electrode approach to calculate the free energy profile for electrochemical protonation of N2 and N adatoms on cuboctahedral Mo13 nanopart...
متن کاملMolybdenum Nitride Catalysts
Effects of the synthesis parameters on the structural properties of molybdenum nitride catalysts, prepared by the temperatureprogrammed reaction of MoO3 with NH3, have been examined. Molybdenum trioxide was heated in flowing NH 3 through two linear heating segments (623 to 723 K then 723 to 973 K) with different space velocities in a 23 factorial design. The temperature limits for these heating...
متن کاملCatalytic hydrodenitrogenation of indole over molybdenum nitride and carbides with different structures
The hydrodenitrogenation (HDN) of indole has been studied over Mo2N and Mo2C with different structures. The difference in activity was modest and the structure of the catalysts exerted a more signi®cant effect than the chemical composition. More evident difference was observed in selectivity, and here the composition was the most important factor. Sonochemically prepared Mo2C was an active cata...
متن کاملSynthesis and Characterization of Ru/Al2O3 Nanocatalyst for Ammonia Synthesis
Ru/Al2O3 catalysts were prepared by conventional incipient wetness impregnation as well as colloid deposition of RuCl3 precursor via in situ reduction with ethylene glycol (polyol) method on alumina support. The samples were characterized by TEM, XRD and TPR techniques. The catalytic performance tests were carried out in a fixed-bed micro-reactor under diffe...
متن کاملSynthesis and characterization of CrN/Mo2N multilayers and phases of Molybdenum nitride
CrNx, MoNx, CrOx, MoOx and CrN/Mo2N multilayer films were deposited by reactive sputtering. Characterization of the coatings was carried out using XRD, XPS, optical profilometer, and nano-indentation. The oxidation of the thin films was studied as a function of annealing temperature. Tribological characterization of the Cr2O3 and the Mo-oxides was carried out as a function of annealing temperat...
