摘要：
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 H-2 ( >773 K), and was found to increase with increasing reduction temperature.
