Research progress of multi-scale porous metal-organic frameworks materials for gas storage and separation
CHEN Di-ming
Abstract：The research progress of porous metal-organic frameworks (MOFs) materials that target for the gas storage and separation was introduced,and its application in CO2 storage/separation and C2H2 gas storage was summarized.It was pointed out that MOFs materials with different pore properties had different effects on CO2 storage and separation and C2H2 gas storage,the performance of the composites could be controlled by controlling the size,shape and functional groups of the MOFs materials.At the same time,the structure-activity relationship of the synthesiczed material by means of single crystal diffraction technique and in situ characterization so as to optimize the performance of MOFs materials.However,most MOFs materials have poor water stability,which could be improved by using an organic ligand containing a hydrophobic group and a high-valent metal cluster (e.g.,Cr3+,Zr4+,etc.) as a molecular-based building unit of MOFs materials.The adsorption selectivity of MOFs materials to specific gas had a large room for improvement,and this problem could be achieved by designing and synthesizing MOFs materials with dynamic adsorption behavior.In addition,the use of molecular simulation technology could really put the structure and function of the material to the design level in the future,thus saving experimental costs.
