Palladium with inorganic materials

Hydrosilylation of butadiene using palladium complexes supported on inorganic materials such as silica and alumina has been carried out (77, 72) however, the supported catalyst is not stable and it is difficult to compare with the soluble catalysts. 

The liquid-phase hydrogenation of various terminal and internal alkynes under mild conditions was largely described with metal nanoparticles deposited/in-corporated in inorganic materials [83, 84], although several examples of selective reduction achieved by stabilized palladium, platinum or rhodium colloids have been reported in the literature.
