From: Protective catalytic layer powering activity and stability of electrocatalyst for high-energy lithium-sulfur pouch cell

Fig. 2

Low-magnification TEM images of (a) Fe-PCL, (b) Co-PCL, and (c) Ni-PCL. High-magnification TEM images of (d) Fe-PCL, (e) Co-PCL, and (f) Ni-PCL. Thin PCL was derived from the carbonization of polydopamine and the subsequent graphitization on the metal surface. g XRD patterns of M-PCL. The XRD patterns of bcc structured Fe, fcc structured Co, and fcc structured Ni metals are well-matched with JCPDS No. 06-0696, 15-0806, and 04-0850, respectively. h Co K-edge XANES and (i) FT-EXAFS spectra of Co-PCL, reference metallic Co foil, and cobalt monoxide (CoO).
