金属有机骨架材料MOFs及其应用.ppt

金属有机骨架材料及其应用 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 Postdoctoral 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 多孔性 大比表面积 结构的多样性 MOFs 合成方法 特点 应用 分类 Design and synthesis of an exceptionally stable and highly porous metal-organic framework This synthesis is achieved by borrowing ideas from metal carboxylate cluster chemistry, where an organic dicarboxylate linker is used in a reaction that gives supertetrahedron clusters when capped with monocarboxylates.
