HAADF-STEM images of a Pt-S-CNT, b Pt-N-CNT, and c Pt-C-CNT, the bright dots (as marked by red arrows) represent typical Pt single atoms. Scale bars, 5 nm. d k2-weighed Pt L3-edge FT-EXAFS spectra for as-prepared Pt-X-CNT in the R space, e core-level XPS spectra for Pt 4 f region, and f corresponding XANES spectra at Pt L3-edge in comparison to Pt foil and PtO2 references.
