摘要: Cobalt-containing SBA-15 supported gold catalysts for low-temperature CO oxidation were prepared and characterized by N-2 adsorption/desorption, X-ray diffraction, transmission electron microscopy, inductively coupled plasma-atom emission spectroscopy photoelectron techniques. The effects of cobalt content on the catalyst activity investigated in detail. Among them, 2% Au/40% Co/SBA-15 shows highest activity, its complete conversion temperature is at 273 K. It was believed that both dispersion Of Co3O4 high surface areas caused contribute to good activities cobalt-containing catalysts. Furthermore, strong metal-support interaction between oxides greatly related catalytic performance. (c) 2005 Elsevier Ltd. All rights reserved.
