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...
متن کاملSynthesis and CO Oxidation Activity of 1D Mixed Binary Oxide CeO2-LaOx Supported Gold Catalysts
One-dimensional (1D) Ce-La nanorods with different La contents (Ce and La in the molar ratio of 1:0, 3:1, 1:1, 1:3, and 0:1) were synthesized by hydrothermal process. Au/Ce-La nanorod catalysts were obtained by a modified deposition-precipitation method. The samples were characterized by N2 adsorption-desorption (BET), ICP, X-ray diffraction (XRD), SEM, TEM, EDX, X-ray photoelectron spectroscop...
متن کاملOxidation 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...
متن کاملFirst Principles Calculations of Supported Catalysts: CO Oxidation on MgO Supported Gold Nanoparticles
Introduction Bulk gold is a chemically inert metal, and had previously been disregarded as a candidate for catalytic applications [1]. Haruta’s pioneering work [2] showed exceptional reactivity on gold nanoparticles of 2-5 nm in diameter. Among reactions, the low temperature CO oxidation [3] on Au has created a strong interest. Model catalyst samples, which consist of planar metal oxide surface...
متن کاملStudy on spinel supported gold catalysts for alcohol oxidation reactions
Gold had been regarded as an inactive metal in catalysis due to its inert chemical nature. However, it was found that when gold is prepared as nanoparticles, it can exhibit surprisingly high activity for various reactions, especially for oxidation reactions [1]. In order to obtain gold nanoparticles (AuNPs), support is commonly used, which can not only help to avoid agglomeration of AuNPs, but ...
