Abstract
The sol-gel method has been applied for supporting Pd nanoparticles (ca.4.8nm) previously synthesized in functionalized ionic liquids 1-n-butyl-3-(3-trimethoxysilylpropyl) imidazolium hexafluorophosphate [PMI.Si.(OMe)3.PF6] and 1-n-butyl-3-(3-trimethoxysilylpropyl) imidazolium bis (trifluorometanosul) imidato [PMI.Si.(OMe)3.N(Tf)2]. The results obtained by the catalyst formed (Pd/IL/SiO2), using acid or base medium was evaluated, as well as the texture of the support material, the activity and recycle. The catalyst Pd/IL/SiO2 synthesized in acidic conditions showed larger pore diameters, which in turn might be responsible for the higher catalytic activity in hydrogenation reactions studied.
