Imprisoned palladium: A unique approach is developed to incarcerate metal clusters with strictly controlled n values within hollow silica nanoparticles. A Pd12L24 spherical complex is used as a template for the hollow silica synthesis. The incarcerated Pd12L24 core is calcinated to give (PdO)n oxide clusters and subsequently reduced to Pdn metal clusters within the protective hollow silica.
