It's difficult to make the functional devices of Metal-organic frameworks (MOFs) due to its inherent flaws such as fragile, thermolabile, etc. However, the porous metal materials has an advantage in a strong resistance to stress and high ductility. The project intends to design and developed a high performance composite porous material and its devices through the proper adjustment both microscopic structure of MOFs and porous metal and make them effective composite. Mainly study the following two topics based MOFs in gas adsorption, separation, and catalytic application-oriented through synthesis the composite material of excellent MOFs with various types of porous metal. ① Explore the synthesis method of such composite materials and composite rules. Strive to obtain a simple and efficient synthetic method of the composite material. ② Study the adsorption and separation performance of the composite porous material to the gas such as CO, NO, CO2, N2, CH4 and H2, and its heterogeneous catalytic performance. Strive to screening several high performance composite materials to achieve functional devices, and to study its application in the treatment of industrial waste gas and organic synthesis. Through this project, new ideas, new theory and new technology in the preparation of such composite materials will be obtained. It is expected to achieve the practical value of such composite in adsorption, separation and catalysis.

金属/有机骨架化合物(MOFs)自身存在易碎、不耐高温等缺点，其功能器件化难度较大，而多孔金属材料具有强的抗压性和高延展性等优势，本项目拟将MOFs和多孔金属复合，通过调节两者的微观结构研制出优良性能的复合多孔材料及其器件。以MOFs在气体吸附分离以及催化等方面的应用为导向，通过合成具有良好性能的MOFs主体与各种类型的多孔金属复合，① 研究此类复合材料的合成方法和复合规律，力争获得不同多孔金属与MOFs复合材料简便、高效的合成方法；② 详细研究复合多孔材料对CO、NO、CO2、N2、CH4及H2等气体的吸附分离性能以及此类材料的非均相催化等性能，力争筛选出几种性能优异的复合材料，实现其功能器件化，并研究其在工业废气处理和催化中的应用。通过本项目研究有望获得制备此类复合材料的新思路、新理论和新技术，以实现此类复合材料在吸附分离以及催化等方面的实际应用价值。
