Pd nanoparticles are synthesized in spherical SiO2 shells (see image), and their catalytic activity for CO oxidation and acetylene hydrogenation is investigated. The activity is observed to be significantly improved compared to traditional supported Pd catalysts, and it is found that the Pd@SiO2 particles are far more resistant to sintering than control samples of Pd supported on silica spheres.
