Progress of preparation and catalytic application of magnesium fluoride with high surface area

This review outlines the synthesis,characterization and catalytic application of MgF2(agnesium fluoride) based materials.The advantage and disadvantage are summarized.Such materials can be used in the systems involving corrosive gases and solvent due to its corrosion resistance and high stability.The catalytic reactions,are chlorine/fluorine exchange reactions,hydrogenation,hydrodechlorination of chlorofluorocarbon,hydrodesulfurization of organic compounds and removal of NOx.The catalytic application of magnesium fluoride itself is limited due to its low surface area and weak acidic properties.The recent development on the synthesis,catalytic application of MgF2 and supported solid acid catalysts is reviewed.Special attention is paid to the controlled synthesis of MgF2(magnesium fluoride) with high specific surface area and tunable acid-base properties.Finally,the importance of research on the preparation of high surface area MgF2 and its application prospects in catalysis is pointed out.
