Fig. 4

A Ion-exchange adsorption isotherms for nitrate in the concentrated region with respect to the highly and weakly charged LDHs, corresponding to Fig. 2c after the Y axis is modified to the corresponding xB value. B The representative ex situ synchrotron powder XRD patterns of the highly charged LDHs (II in A) (a) and closer inspection of the wet-XRD patterns of the highly charged LDHs (b) and weakly charged LDHs (c). The Roman numerals I–V correspond to the description of A. C The representative thermogravimetry-differential thermal analysis (TG-DTA) profiles of the highly charged LDHs (II in A) (a) and the total water content and the structured water content in the highly charged LDHs (b) and the weakly charged LDHs (c). Structured water is referred to as SW. Source data are provided as a Source Data file.
