Preparation of polymer-embedded NH2-UiO-66 MSs.
ZrCl4 (0.48 g), NH2-BDC (0.37 g), and
polysulfone (PSF, 4.80 g) were dissolved in DMF (80 mL). For dissolving,
the suspension was stirred for 4 h. The obtained transparent solution
was transferred to a Teflon-lined stainless steel autoclave. For
crystallization, the autoclave was thermally treated at 120 °C for 24 h.
After natural cooling to room temperature, the formed powders were
isolated by centrifugation at 6000 rpm for 6 min. Eventually, the
obtained powders were washed by DMF and methanol for several times, and
dried in vacuum at 100 °C overnight.
