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 H-2-rich fuels were measured in the temperature range from 25 degrees C to 300 degrees C. At 2500 ppm of carbon monoxide, COPt-SiO2 aerogels showed good activities in a wide range of temperatures maintaining less than 20 ppm at 125-250 degrees C. (c) 2007 Elsevier B.V.
