Platinum nanoparticles have been loaded on mesoporous silicas or aluminosilicates, and silylated mesoporous silicas. The metal is well-dispersed with uniform diameter of 1-3 nm inside channels of mesoporous supports. The high catalytic activities on hydrogenation of aromatics are observed on Pt/SiO2 composites that may be related to the silylation of intrachannel surface for the generation of binding sites to Pt precursor ions.
