Halogen-modified metal–organic frameworks for efficient separation of alkane from natural gas

Pillar-layered MOFs, Ni (BDC)(DABCO) 0.5 (DMOF-X), modified by halogen atoms (F, Cl, Br), were investigated for CH 4 /C 2 H 6 /C 3 H 8 separation performance. DMOF-Cl demonstrated great potential as an adsorbent for the efficient separation of C 3 H 8 and C 2 H 6 from CH 4 .
