Abstract

Abstract : A catalyst containing platinum nanoparticles embedded into the walls of a mesostructured silica framework is highly active in alkene hydrosilylation and does not lead to Pt leaching. Abstract : A catalyst containing small ( ca. 2.5 nm) and crystalline Pt nanoparticles embedded into the walls of a mesostructured silica framework was found to be highly active in alkene hydrosilylation reaching TONs of ca. 10 5 . More importantly, no Pt leaching was detected. This result is remarkable because Pt leaching is a recurrent problem in alkene hydrosilylation, which often prevents heterogeneous catalysts from being used industrially. This result is in contrast to the significant Pt leaching observed for other Pt/SiO2 catalysts.
