Abstract

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