Morphology control synthesis of Cr-benzenedicarboxylate MOFs for the removal of methylene blue

Propionic acid could efficiently affect the formation of Cr-benzenedicarboxylate metal-organic frameworks (MOFs), giving rise to yielding products with various structures. Generally, nano-sized crystals of MIL-101(Cr) can be prepared with comparatively lower concentration of propionic acid (0.6 ​M), which possessed high porosity (SBET ​= ​2720 ​m2/g). The hierarchically porous (HP) MIL-101(Cr) was obtained with medium concentration of propionic...
