CO oxidation over embedded Pt nanoparticles on Al 2 O 3 with Al coordination flexibility

A Pt/Al O catalyst is prepared on pentahedral Al-rich Al O with flexible Al coordination, enabling embedment of Pt nanoparticles into the support. The embedded Pt nanoparticles show higher CO oxidation performance than the surface Pt species at appropriate GHSV, suggesting a promising way to tune th...

Zusammenfassung:A Pt/Al O catalyst is prepared on pentahedral Al-rich Al O with flexible Al coordination, enabling embedment of Pt nanoparticles into the support. The embedded Pt nanoparticles show higher CO oxidation performance than the surface Pt species at appropriate GHSV, suggesting a promising way to tune the properties of the supported Pt catalysts.
