摘要
Platinum-silica catalytic materials were prepared by the sol-gel method using tetraethoxysilane (TEOS) and various platinum precursors. Important effect of the preparation method on textural and metallic dispersion was found. When platinum chlorides are the precursors a very low metal dispersion is obtained; on the contrary using free chloride platinum compounds highly dispersed materials are prepared.
