摘要：
Comparative results (specific area, metallic dispersion, and activity in the carbon monoxide oxidation) on sol-gel and impregnated Pt/TiO2 catalysts are presented. In order to explain the important differences between the two preparations, among them high resistivity of sol-gel catalyst to sintering, the formation of anchored and/or partially buried particles into the support is proposed.
