Selective oxidation and ammoxidation of propene on bismuth molybdates, ab initio calculations
In this paper we use first principles quantum mechanical methods (B3LYP flavor of density functional theory) to examine the mechanism of selective oxidation and ammoxidation of propene by BiMoOx catalysts. To do this we use finite clusters chosen to mimic likely sites on the heterogeneous surfaces of the catalysts. We conclude that activation of the propene requires a Bi(V) site while all subse...
متن کاملStructure and surface kinetics of bismuth adsorption on Si(001).
X-ray standing wave measurements, along with local-density molecular cluster calculations, were used to determine the surface structure of the low-coverage Bi/Si~001! surface. The 232 Bi phase, predicted by theory to be the stable low-coverage structure, was found experimentally to be a metastable phase and was observed to have a thermally activated irreversible phase transition to the stable 1...
متن کاملOxygen surface exchange kinetics of erbia-stabilized bismuth oxide
The surface oxygen exchange kinetics of bismuth oxide stabilized with 25 mol% erbia (BE25) has been studied in the temperature and pO2 ranges 773–1,023 K and 0.1– 0.95 atm, respectively, using pulse-response O–O isotope exchange measurements. The results indicate that BE25 exhibits a comparatively high exchange rate, which is rate determined by the dissociative adsorption of oxygen. Defect chem...

متن کاملNanocalorimetry of Bismuth Nanoparticles
The properties of nanosized bismuth particles are investigated using a nanocalorimetric technique. A brief description of the experimental method and data analysis procedures is reported. Bismuth nanoparticles are found to melt at a temperature below that of bulk material, but higher than expected using the standard model. Also included is the results of a finite element analysis and simulated ...
