Fig. 2

A–C HAADF-STEM images of Pt-Bi/Mo/ZSM-5 surface: the circles in (C) indicate the in-channel Mo species. D The EDS spectra of the trimetallic Pt-Bi/Mo/ZSM-5 catalyst. Scale bar, 50 nm (E) The line scan of Pt and Bi element along a particle of a bimetallic Pt-Bi/ZSM-5 catalyst. Scale bar, 25 nm. F The comparison of XPS spectra of Bi/ZSM-5 and Pt-Bi/ZSM-5 catalysts on Bi 4f. G The comparison of XPS spectra of Pt/ZSM-5 and Pt-Bi/ZSM-5 catalysts on Pt 4f.
