Title
Co-promoted Pt catalysts supported on silica aerogel for preferential oxidation of CO
Abstract

Pt and Co doped silica aerogels have been synthesized by sol–gel method and subsequent supercritical drying. Wet–gel state of silica was used in the adsorption process in order to accommodate Pt and Co. Catalytic activities for preferential oxidation of CO in H2-rich fuels were measured in the temperature range from 25oC to 300oC. At 2500 ppm of carbon monoxide, CoPt–SiO2 aerogels showed good activities in a wide range of temperatures maintaining less than 20 ppm at 125–250oC.
