Abstract

Pt/SiO₂ reduced at 1073 K exhibited a high catalytic activity in propane dehydrogenation, primarily attributed to the electronic modification of Pt nanoparticles by a strong metal-support interaction (SMSI) effect. The SMSI was observed in the Pt/SiO₂ system following direct reduction in H₂ (>773 K), and was found to increase with increasing reduction temperature.
