      Chromia-Based Catalyst in the Chlorine/Fluorine Exchange Reactions for 
      Unsaturated Fluorocarbons.

AB  - Hydrofluoroolefins (HFOs) and cyclic hydrofluorocarbons (c-HFCs) have been the 
      most favored alternatives of the ozone depletion substances; however, because of 
      the poor performance of the present chlorine/fluorine (Cl/F) exchange catalysts, 
      the development and production of HFOs and c-HFCs are hindered. Here, we first 
      report a novel and facile route to fabricate high-performance Cl/F exchange 
      catalysts via a metal-organic framework (MOF) carbonization method. The 
      MOF-derived catalyst not only has high selectivity but also can significantly 
      lower the reaction temperature. Moreover, benefiting from the stable structure 
      and coke-inhibiting ability, the MOF-derived catalyst has a long service life 
      compared with the traditional precipitation method. Furthermore, the nanoscopic 
      MOF-derived catalyst can greatly reduce the Cr dosage, which would help to 
      minimize the risk of Cr contamination.
