Abstract

A Pt/Al₂O₃ catalyst is prepared on pentahedral Al-rich Al₂O₃ 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.
