Fig. 3: Characterization of CIN based on POM clusters and ionic chains.
From: Single-layer cluster ionic-chain networks with tetragonal pores

a Small-angle XRD results of Mn-CIN. The a and c peaks are attributed to interlayer stacking of the monolayer network, while the b peak arises from the ordered arrangement of adjacent clusters within the monolayer network. b XRD results of Mn(H2PO4)2·2H2O crystals and Mn-CIN. c XANES spectra of Mn-CIN. d WT representation of the EXAFS signal. e The XPS data of Mn 3 s in Mn(H2PO4)2·2H2O and Mn-CIN. f The XPS data of W 4 f in PW10Mn2 clusters and Mn-CIN. g The band gaps of Mn(H2PO4)2·2H2O crystals, PW10Mn2 clusters, and Mn-CIN obtained from UV-vis diffuse reflectance spectra.
