摘要：

Platinum and palladium silica supported catalysts were prepared by the sol-gel method using as metallic precursors the square planar complexes t[MCl2(NH3)2] with M = Pt or Pd. The catalysts were synthesized at pH = 3 and 9. If the preparation occurs in acid medium, the resulting solids show uniform microporous structure with BET areas > 500 m2/g. However, if the experiment is made in a basic medium, the resulting solids show non-homogeneous pore size distribution and BET areas < 100 m2/g.
