Fig. 1: Bidirectional continuous interlayer spacing regulation of Pt, Ce–MoS2.
From: Bidirectional and reversible tuning of the interlayer spacing of two-dimensional materials
a Schematic diagram of 2D Pt, Ce−MoS2 interlayer spacing regulation. With Pt inserting and eluting, the chemical bonds are formed reversibly (indicated by the blue or red shadow areas), resulting in the compression and expansion of the interlayer spacing (indicated by the arrow direction). b Interlayer spacing regulation of MoS2 via Ce doping (blue dashed line), Pt intercalating (red dashed line), and Pt eluting (green dashed line). Error bars represent standard deviation over 26 independent replicates at least. c TEM images of the layered edges of Pt-intercalated and Pt-eluted MoS2 and the intensity profiles in the bottom panels corresponding to the areas marked by white rectangles in the upper panels. d means the average interlayer spacing, which is obtained from the average distance between two neighboring peaks in the intensity profiles. Scale bar, 5 Å. d In situ SRXRD spectra of MoS2 with Pt intercalating and Pt eluting.
