| Résumé: | Last years nanosized gold particles attract much attention as a component of industrially perspective catalysts for somereactions as CO oxidation, NO reduction etc. We studied several systems including gold based on different syntheticzeolites pure or doped with another metals (Fe, Na). It was shown by different techniques (XPS, UV-Vis spectroscopy,TPR) that intrinsic properties of zeolites used and gold system preparation method influence significantly on thecontribution of different gold species (ions, clusters and particles). For mixed Au-Me-zeolites activity level and dynamicof CO conversion with time in steam and temperature depends on nature of zeolite and specificity of Au-Me interaction.All binary metal systems were found to be activated in different degree during catalytic activity test due to mutualinteraction of gold with second metal. Extremely high level of CO conversion and low dependence of activity ontemperature was observed for Au- Fe- H- and Na-Y zeolites. The change in contribution of gold nanoparticles wasobserved after sample contact with CO. В фонде НТБ ТПУ отсутствует |
