Abstract

The preparation and characterization of highly structured material containing regularly distributed Pt nanoparticles through the controlled growth of a mesostructured silica matrix around Pt colloids was reported. The used materials were fully characterized using several analytical techniques, thus leading to a highly active Pt containing nanostructured catalyst for the propene hydrogenation reaction. The experiment included the synthesis of the material by reaction of the aforementioned solution with an acidic aqueous solution of Pluronic P123 surfactant and TEOS as the precrusor of the oxide matrix. The results incorporate that the as-synthesized material showed the successful incorporation of Pt nanoparticles while retaining superior material mesostructuration, where the removal of surfactant was achieved by calcination under dry air at 593 K.
