Figure 6. (A) Schematic of synthesis of iron catalysts using ZIF-8 and MOF-5 as precursors; (B) P1 and P2 pathways of CTH reaction on Fe(II)-plN4 and Zn(II)-plN4, compared with P3 pathway on Fe(II)-plN3; (C) k2-weighted Zn K-edge and EXAFS spectra of Fe-ZIF-8-800; (D) Catalytic performance and TOF of various catalysts^[63].
