Abstract

A novel well-dispersed Pd@HHSS catalyst was synthesized by reduction of Pd(OAc)₂ immobilized on HHSS we reported. When the ratios of Pd/SiO₂ were 5 : 100 and 10 : 100, the Pd nanoparticles size was about 5-10 nm. The Pd@HHSS catalyst (Pd/SiO₂ = 10 : 100) showed high catalytic activity in Suzuki-reaction with yields of 91-99% and the catalyst is reusable after four successive cycles without obvious loss of catalytic activity.

Keywords: heterogeneous catalysis; hierarchical hollow silica spheres; palladium nanoparticles.
