Chem. 3, … We investigated further the CO adsorption behaviour of the catalysts using Fourier-transform infrared (FTIR) spectroscoy to provide additional information about the dispersion and oxidation state of Pt. Figure 3 shows that, for sample B, the adsorption of CO produces a strong vibration band at 2,030 cm−1 and two … Ver más The single-atom Pt1/FeOx catalyst (denoted as sample A, with a Pt/Fe atomic ratio of 1/1430 and a Pt loading of 0.17 weight percent (wt%)) was prepared by a co-precipitation method reported previously for … Ver más Subångström-resolution, aberration-corrected scanning transmission electron microscopy (STEM) was used to characterize the dispersion and configuration of the Pt clusters in the catalysts. Individual … Ver más Consistent with the HAADF image analyses, X-ray diffraction patterns of samples A and B (Supplementary Fig. S4) did not show any Pt … Ver más We chose CO oxidation and PROX as probe reactions to investigate the catalytic performance of FeOx-supported single Pt atoms, as such … Ver más
