A microporous yttrium metal–organic framework of an unusual nia topology for high adsorption selectivity of C2H2 and CO2 over CH4 at room temperature

Abstract

A new microporous yttrium metal–organic framework Y-H3TDPAT [H6TDPAT = 2,4,6-tris(3,5-dicarboxylphenyl-amino)-1,3,5-triazine] with Lewis basic sites on the pore surface was solvothermally synthesized and structurally determined as an unusual (6,6)-connected nia topology. The small pores and the Lewis basic sites within the desolvated Y-H3TDPAT have improved the affinity for C2H2 and CO2 which has been revealed in their large isosteric heats of adsorption (38.2 and 30.9 kJ mol−1). In addition, highly selective separation of C2H2/CH4 and CO2/CH4 at room temperature makes Y-H3TDPAT possess a potential application in natural gas purification.
