Abstract：In this study,two MOFs materials(SNNU-505-Zn and SNNU-505-Co)were synthesized,and their crystallinity,purity,thermal stability,pore structure,specific surface area,and adsorption separation performance for C6 alkane isomers were investigated.The results indicate that the specific surface areas of SNNU-505-Zn and SNNU-505-Co,measured using CO2 as a probe molecule at 195 K,were 199.71 m2/g and 52.768 m2/g,respectively.At 298 K and 10 kPa,the adsorption capacities of SNNU-505-Zn and SNNU-505-Co for n-hexane were 71.75 mg/g and 49.79 mg/g,while those for 3-methylpentane(3MP)were 37.99 mg/g and 40.78 mg/g,respectively.The adsorption selectivities of SNNU-505-Zn and SNNU-505-Co for nHEX/3MP at 298 K and 10 kPa were 46.63 and 1.71,respectively.Notably,SNNU-505-Zn exhibited higher selectivity for nHEX/3MP compared to most other adsorbents.
