a, Illustration of the structural distortion of CoPc on different-diameter CNTs, assuming CoPc is fully elastic. b–e, HAADF-STEM (b) and EDS elemental mapping for overlap (c) N (d) and Co (e) of CoPc/SWCNTs. f, Aberration-corrected HAADF-STEM of CoPc/SWCNTs showing isolated cobalt atoms (red circles) on the SWCNT surface. Scale bars: b, 20 nm; f, 5 nm.
