Imprisoned palladium : A unique approach is developed to incarcerate metal clusters with strictly controlled n values within hollow silica nanoparticles. A Pd 12 L 24 spherical complex is used as a template for the hollow silica synthesis. The incarcerated Pd 12 L 24 core is calcinated to give (PdO) n oxide clusters and subsequently reduced to Pd n metal clusters within the protective hollow silica.
