Figure 7
Scanning transmission X-ray microscopy (STXM) C K-edge optical density images of (a) ALD600Pt/Mo2C, (b) ALD600Pt/Mo2C/methanol and (c) Mo2C/methanol. Images were averaged from all stack images at the C K-edge; the enclosed color lines indicate the regions of interest on the samples for extracting X-ray absorption near-edge structure (XANES) spectra; (d) C K-edge spatially resolved XANES spectra from the selected regions of interest in (a–c). Vertical dashed lines in the figures indicate spectral regions of interest. ALD, atomic layer deposition.
