金属有机骨架材料MOFs及其应用

1、金属有机骨架材料MOFs及其应用研究背景早在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（MOFs）是由含氧、氮等的多齿有机配体（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 Omar M. Yaghi received his Ph.D. from the University of Illinois-Urbana (1990) with Professor Walter G. Klemperer. He was an NSF Pos

2、tdoctoral Fellow at Harvard University (1990-92) with Professor Richard H. Holm. He has been on the faculties of Arizona State University (1992-98) and University of Michigan (1999-2006). His current position is the Jean Stone Professor of Chemistry at UCLA. 催化剂气体储存吸附分离含氮杂环含羧基含氮杂环与羧基分层、扩散法水热法搅拌合成法多孔
