a Pt L3-edge XANES spectra; b Comparison between the experimental and calculated spectra using the pyramidal Pt-3S model (inset). The colour scheme used is as follows: light-cyan for Mo; yellow for S; white for Pt. Outer MoS2 atoms are omitted for the sake of clarity; c FT-EXAFS spectra of various catalysts. Dotted lines represent the fitting of the FT-EXAFS spectra; d False-coloured micro-CT image of the 3D structure of the M1-MoS2 array on graphite felt; e Mercury intrusion porosimetry and f Compressive strain–stress curves of blank GF and M1-MoS2-GF. Inset shows the comparison of the stress at 50% strain and compressive modulus at 15 ~ 20% strain. Error bars (SD) were presented from 5 individual tests. M = Co for (d–f); Scale bar: d, 100 µm.
