Abstract

Platinum‐oxide nanoparticles were prepared through the radio‐frequency (RF) discharge sputtering of a Pt electrode in an oxygen atmosphere. The structure, particles size, electronic properties, and surface composition of the RF‐sputtered particles were studied by using transmission electron microscopy and X‐ray photoelectron spectroscopy. The application of the RF discharge method resulted in the formation of highly oxidized Pt4+ species that were stable under ultrahigh vacuum conditions up to 100 °C, indicating the capability of Pt4+–O species to play an important role in the oxidation catalysis under real conditions. The thermal stability and reaction probability of Pt4+ oxide species were analyzed and compared with those of Pt2+ species. The reaction probability of PtO2 nanoparticles at 90 °C was found to be about ten times higher than that of PtO‐like structures.
