Figure 2. Structural and surface-chemical analysis of ZIF-67 and Mn-ZIF-67. (A) Experimental diffractograms ZIF-67 and Mn-ZIF-67 with the simulated ZIF-67 reference; (B) XPS spectra of Mn-ZIF-67; (C) N 1s region of Mn-ZIF-67; (D) overlaid O 1s spectra of ZIF-67 and Mn-ZIF-67; (E) Mn 2p region of Mn-ZIF-67; and (F) directly compared Co 2p spectra of ZIF-67 and Mn-ZIF-67. ZIF-67: Zeolitic imidazolate framework-67; XPS: X-ray photoelectron spectroscopy.
