Summary

A series of silica aerogels containing metal Cu or Co in nanoscale have been prepared by sol-gel process and supercritical drying. The resulting aerogels were characterized using TEM, XRD, elemental analysis and nitrogen adsorption analysis. Their catalytic behavior for oxidation of CO have been investigated. The results indicate that Cu-SiO2 or Co-SiO2 aerogels have high activity at 100°C-400°C, whereas the pure SiO2 aerogels has no activity for this reaction.
