摘要：The aim of this paper is to investigate the influence of the mineralizers chlorine ion (Cl-) and fluorine ion (F-) on the structure formation of porous chromium-benzenedicarboxylates (Cr-BDCs). It was proved that Cl- plays a role as mineralizer which is similar to F- that can increase the crystallinity of MIL-101. In contrast, the MIL-101 phase cannot be transformed into the MIL-53 phase without mineralizer. The phase-transition occurs only after the addition of the mineralizer (Cl- or F-) to the system. The results suggest that the mineralizer is the key component affecting the phase-transition of Cr-BDCs.
