a PXRD patterns; (b) Raman spectra; (c) pore size distribution curve; (d) high-resolution N 1 s XPS spectra; (e) XANES spectra; (f) FT-EXAFS spectra; FT-EXAFS fitting curves in (g) R space and (h) k space; (i) WT-EXAFS plots of Zn1/h-OPNC and Zn1/h-OPNC900. The insets in (g) show the Zn-N3 (top) and Zn-N4 (bottom) models, respectively.
