“…2d, the XRD patterns of ZIF-8 showed seven main diffraction peaks at around 7.2°, 10.3°, 12.6°, 16.3°, 17.9°, 24.4°, and 26.6° corresponding to the (011), (002), (112), (013), (222), (233), and (134) diffraction planes, respectively. 45 As for as-synthesized PDA/SA-ZIF-8 and H-PDA/SA-ZIF-8, the peak positions matched well with ZIF-8, implying that the target materials had been successfully prepared. The deposition of salicylaldoxime and the etching of the material did not cause any changes in crystallinity.…”
