Fig. 1. Gels and monolithic particles of UiO-66. (a) ‘Non-flowing’ gels of UiO-66 synthesized from ZrOCl2·8H2O and H2bdc (Table S1,† entry 10). (b and c) Optically transparent monolithic xerogel particles obtained by crushing ‘non-flowing’ gels dried in air at 200 °C. Prior to drying, the gels were washed and solvent-exchanged with ethanol. Scale bar = 100 μm (see also Fig. S1†).
