Figure 2. (A, B) HAADF-STEM images of Pt8Ag4 clusters/CNTs. (C) XANES and (D) EXAFS spectra of Pt8Ag4 clusters/CNTs, PtO2 and Pt foil. (E) High-resolution XPS Pt 4f spectra and (F) Ag 3d spectra in Pt8Ag4 MOCs/CNTs and Pt8Ag4 clusters/CNTs. CNT: Carbon nanotubes; MOC: metallic organic clusters; XPS: X-ray photoelectron spectroscopy.
