金属有机骨架材料MOFs及其应用课件.ppt

1、金属有机骨架材料及其金属有机骨架材料及其应用应用研究背景早在20世纪90年代中期，第一类MOFs就被合成出来，但其孔隙率和化学稳定性都不高 目前，已经有大量的金属有机骨架材料被合成，这些金属有机骨架中多数都具有高的孔隙率和好的化学稳定性 金属有机骨架（金属有机骨架（MOFsMOFs）是由含氧、氮等的）是由含氧、氮等的多齿有机配体（大多是芳香多酸和多碱）多齿有机配体（大多是芳香多酸和多碱）与过渡金属离子自组装而成的配位聚合物与过渡金属离子自组装而成的配位聚合物 Omar M.Yaghi received his Ph.D.from the University of Illinois-Urban
