Ozone Decomposition and Acetone Oxidation on Manganese Oxide Catalysts
… temperature-programmed reduction (TPR), and oxygen chemisorption. The use of these techniques allowed better understanding of the nature of the catalysts. Activity tests were carried out in the acetone oxidation reaction and it was found that the usage of ozone substantially reduced the …

Characterization of gold catalysts for methanol synthesis
… small gold crystallites. In this study oxygen chemisorption was used as an additional method to characterize supported gold catalysts to complement electron microscope techniques. Agreement between the results from these different methods was obtained only with regard to the order of …

In situ laser Raman studies of the mechanism of ethanol oxidation over supported molybdenum oxide
… was studied on MoO₃ on SiO₂, Al₂O₃ and TiO₂. Oxygen chemisorption and temperature programmed reduction (TPR) results indicated that the molybdenum oxide - support interaction decreased in the order: TiO₂ > Al₂O₃ > SiO₂. Temperature programmed surface reaction (TPSR) of adsorbed ethanol was …

Gold catalysts prepared by ion exchange for use in ethylene glycol oxidation: An exploratory study
… Microscopy (TEM), X-Ray Diffraction (XRD) and oxygen chemisorption. TEM results were used to calculate average crystallite sizes as well as to give an indication of size distributions. Measurable XRD gold peaks were only visible for supported carbon catalysts, and the crystallite sizes …

Structure and Ozone Decomposition Reactivity of Supported Manganese Oxide Catalysts
… laser Raman spectroscopy, temperature programmed oxygen desorption, surface area measurements, extended and near edge x-ray absorption fine structure (EXAFS and NEXAFS) showed that the manganese oxide was highly dispersed on the surface of the supports. EXAFS spectra suggest that the manganese …
