ENCAPSULATED PYRIDAZINE Cr(III) COMPLEXES PREPARED BY BIOSORBENTS SUPPORTED IN ZEOLITES

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...

Polymer-supported metal complex oxidation catalysts

Bbstract Recent developments involving polymer-supported metal complexes as catalysts in oxidation reactions, using dioxygen, hydrogen peroxide, alkyl hydroperoxides, hypochlorite anion and iodosobenzene as oxidants are reviewed. binding of dioxygen, and in catalysis, along with the structurally closely related metallo-phthalocyanines, oxidative polymerization catalysed by polymer-supported cop...

Study 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 ...

Catalytic Oxidation of Carbon Monoxide by Cobalt Oxide Catalysts Supported on Oxidized-MWCNT

Cobalt oxide catalysts supported on oxidized multi-walled carbon nanotubes (MWCNT) for the low-temperature catalytic oxidation of carbon monoxide were prepared by an impregnation-ultrasound method. These catalysts were characterized by N2 adsorption/desorption, TEM, XRD, Raman, and H2-TPR methods. The XRD and Raman results indicated that the phase of the synthesized cobalt...
