Figure 3. Comprehensive physical characteristics for structural analysis. (A) the N2 adsorption/desorption isothermals of ZIF-L NA, ZIF-L bulk, Fe-N-C NA, and Fe-N-C bulk; (B) PXRD patterns of Fe-N-Cs; (C and D) Raman spectra of Fe-N-C NA and Fe-N-C bulk, respectively; (E and F) XPS spectra for N 1s orbits of Fe-N-C NA and Fe-N-C bulk, respectively. NA: Nano-assembly; PXRD: powder X-ray diffraction; XPS: X-ray photoelectron spectroscopy.
