Figure 3: XRD patterns of pure
ZIF-62 and silver-doped ZIF-62 crystals
A further probe into the
structure of the resulting Ag-doped ZIF-62 was performed to understand
the effect of silver adsorption onto the ZIF-62 structure. From the XRD
results in Figure 3, it was found that there was no significant
difference between synthesized ZIF-62 particles with the Ag-doped ZIF-62
particles, with the exception of the lower bIm ratio (ZIF-62-a). For the
Ag-ZIF-62 at this lower bIm ratio, some small new peaks were seen, which
may indicate the introduction of slight structural change, though the
bulk ZIF-62 peaks are still present. This may also indicate that the
silver interaction during adsorption towards the overall crystal
structure of the ZIF-62 is dependent on the benzimidazole amount within
the structure.
