摘要：

Pt-Sn supported catalysts were prepared by the sol-gel method. The solids were characterized by FTIR and UV-VIS spectroscopy and N2 adsorption analysis. The platinum showed a deformed octahedral symmetry, tending to come to the surface as metallic platinum and forming small particles anchored to the support.
