Figure 5. Pore volumes in the different diameter ranges deduced from the
pore size distributions given in Figure 4.
Figure 6 shows SEM images of UiO-66 and UiO-66-nGr2, which confirmed
that UiO-66 is deposited on nGr flakes and that “wall structures” of
UiO-66 are assembled horizontally. This morphology might increase the
accessibility of the adsorbates to the UiO-66 adsorption sites/pores.
