Fig. 2: Characterizations of the PCN-222@PCCs.

TEM images of PCN-222@PCC-4 (a) and PCN-222@PCC-5 (c). STEM image and EDX element mapping of a single particle of PCN-222@PCC-4 (b) and PCN-222@PCC-5 (d). PXRD patterns (e), Zeta potential measurements (Data are presented as the mean ± SD.) (f), and FT-IR spectra (g) of pristine PCN-222, PCN-222@PCC-4, and PCN-222@PCC-5. The XPS spectra show Zr 3d3/2 and 3d5/2 binding energy of PCN-222, PCN-222@PCC-4, and PCN-222 (h). N2 adsorption isotherms of PCN-222@PCCs. The N2 uptake was normalized to the same mass of PCN-222 (i). The surface density of PCN-222@PCCs (j). Photostability of PCN-222@PCCs in benzylamine methanol solution (k). Space-filling illustrations generated from molecular dynamics simulations showing the representative structures of PCN-222@PCC-4 (l) and PCN-222@PCC-5 (m).
