不同孔径的阴离子柱撑金属有机骨架材料分离 C2H2/C2H4
C2H2/C2H4 separation of anion-pillared metal-organic frameworks with different pore sizes
摘要
Abstract
Two anion-pillared metal-organic frameworks CuNbOF5-TPPY and CuSiF6-TPPY(5,10,15,20-tetra(4-pyridyl)-21H,23H-porphine)with different pore sizes(0.68 nm and 0.56 nm)were synthesized by two anion pillars NbOF52-and SiF62-with different lengths.The structure of the material was characterized by XRD,TG,and N2 adsorption-desorption.The ability of the two materials to adsorb and separate C2H2/C2H4 was researched by single-component gas adsorption and mixed-gas breakthrough experiments.The result shows that CuSiF6-TPPY with the smaller pore size has higher separation ability.The C2H2/C2H4 selectivity can be up to 4.41 at 298 K and 1 × 105 Pa.Furthermore,CuSiF6-TPPY maintains excellent repeatability and regenerability after multiple adsorption-desorption cycles.关键词
