Strong metal-support interaction between Pt and SiO2 following high-temperature reduction: a catalytic interface for propane dehydrogenation

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 (&gt...

Beschreibung
Zusammenfassung:	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.
