摘要：

Ruthenium catalysts on silica and alumina were synthesized by the sol-gel process, using tetraethoxysilane, aluminum trisecbutoxide and [RuCl5(H2O)]-2. The catalysts were characterized by infrared spectroscopy (FTIR) and diffuse reflectance (UV-Vis). The spectroscopic studies showed that when the ruthenium is supported on silica, part of the metal is incorporated in the network, giving BET areas up to 530 m2/g. When the support is alumina, the metal does not penetrate the alumina network and the BET area is < 50 m2/g.
