Kinetic models of CO oxidation on Pd-containing catalysts (with and without SO2

Oxidation of CO and Methanol on Pd-Ni Catalysts Supported on Different Chemically-Treated Carbon Nanofibers

In this work, palladium-nickel nanoparticles supported on carbon nanofibers were synthesized, with metal contents close to 25 wt % and Pd:Ni atomic ratios near to 1:2. These catalysts were previously studied in order to determine their activity toward the oxygen reduction reaction. Before the deposition of metals, the carbon nanofibers were chemically treated in order to generate oxygen and nit...

In Situ XAS Investigations of Chemical Oscillations in the Oxidation of Co on Supported Pd Catalysts

CO oxidation on TiO2 supported gold catalysts

The aim within this project was to optimise the CO oxidation over TiO2 supported gold catalysts, focusing on two different preparation methods; deposition precipitation (DP) and photodeposition (PD), using different types of TiO2 and varying the theoretical gold loading. The catalyst were characterised with TEM (size) and ICP-AES (loading). For DP catalysts, the support is important for high ac...

Oxidation of SO2 over Supported Metal Oxide Catalysts

A systematic catalytic investigation of the sulfur dioxide oxidation reactivity of several binary (MxOy/TiO2) and ternary (V2O5/ MxOy/TiO2) supported metal oxide catalysts was conducted. Raman spectroscopy characterization of the supported metal oxide catalysts revealed that the metal oxide components were essentially 100% dispersed as surface metal oxide species. Isolated fourfold coordinated ...
