Rezumat:

Herein we report the observation of the full catalytic cycle of CO oxidation with N2O on cationic platinum clusters for Ptn+, n=6-8, in the gas phase studied by Fourier-transform ion cyclotron resonance (FT-ICR) mass spectrometry. Platinum is the key catalytic metal for a variety of industrial and environmental applications, for example, it catalyzes the oxidation of CO with O2 in catalytic converters. This reaction has been studied in detail on surfaces.
