Fig. 2: Structure characterizations of Pt, Ce–MoS2.
From: Bidirectional and reversible tuning of the interlayer spacing of two-dimensional materials
a Corrected ADF–STEM image of Pt, Ce–MoS2. b As recorded and c corrected cross-sectional ADF–STEM images of Pt, Ce–MoS2 at the edge site. Yellow circle: Ce atoms and Red circle: Pt atoms. Arrow: selected area corresponding to the line intensity profile shown in e. d, e Line intensity profiles in the selected regions in image a and c along I‒Iʼ, II‒IIʼ, III‒IIIʼ, IV‒IVʼ. f Pt L3-edge EXAFS fitting results of Pt, Ce–MoS2 in q space. g k2-weight Fourier transformation of Pt L3-edge EXAFS. The EXAFS oscillations were fitted according to single-atom scattering equation, using the FEFF models.
