一种3D开放骨架多孔配位聚合物材料的合成、结构及其吸附性质研究
Synthesis,structure,and adsorption properties of a 3D open porous metal-organic frameworks
摘要
Abstract
Metal-organic frameworks(MOFs)have potential application in gas storage and many other ar-eas.Syntheses of high stability MOFs became an important topic,due to the inevitable demand for high-stability skeletons in practical application.In this work,a three-dimensional open porous framework,namely Complex 1([Zn2(2-MeBDC)2(TED)]·x G),was solvothermally synthesized by introducing a methyl de-rivative of terephthalic acid(2-methylterephthalic acid,2-MeBDC)as the carboxylic ligand,and 1,4-diazabi-cyclo[2.2.2]octane(TED)as the nitrogen-containing ligand.Structural analyses show that the material structure contains classical the Zn2 paddle wheel units,with pores along the a,b,and c axes,respectively.Thermal stability analyses show that the material can maintain stability up to 260℃,and the porous frame-work can still be preserved after guest molecules removal.Research and analysis on the pore structure and ad-sorption properties of Complex 1 indicate that the pores are sized around 1 nm,the sorption of N2 follows a type I isotherm with a BET surface area of 1350 m2·g-1.Meanwhile,this type of MOF material has a certain adsorption capacity for hydrogen and carbon dioxide,indicating potential applications in hydrogen storage and carbon dioxide capture.关键词
