Merging a colloidal approach for the synthesis of Pt nanoparticles and a supramolecular pathway for generating mesostructured oxides can provide via a one-pot synthesis a well-defined, active, and stable heterogeneous catalyst. This material contains regularly distributed Pt nanoparticles along the channel pores of a highly ordered silica matrix.
