Fig. 4: Continuous-flow reactor setup for the synthesis of UiO-66 using scCO2.

The diagram identifies key components including the thermocouple (TC), counter-current mixer, heating elements, and back-pressure regulator (BPR), which collectively enable rapid mixing, efficient heat transfer, and stable supercritical conditions necessary for scalable MOF production.
