the effect of reaction mixture movement on the performance of chromium-benzenedicarboxylate, mil-101(cr), applicable for co2 adsorption through a new circulating solvothermal synthesis process

The primary objective of the present work was to investigate the effect of fluid movement on synthesized chromium-benzenedicarboxylate, mil-101(cr), quality through a set of experiments performed in a circulating tube reactor using an interval schedule, i.e., circulation stopped periodically. the results revealed that using 30 s pump-on period resulted in cubic crystals while setting this parameter on 90 s created an agglomerated structure. in the optimum condition, the synthesized mil-101(cr) had the bet surface area 2354 m2/g, pore volume 1.94 cm3/g, and co2 adsorption capacity 10.9 mmol/g. using microwave irradiation to activate the produced crystals improved crystal bet surface area to 3860 m2/g.
