Abstract

Simultaneous improvement in adsorption selectivity and capacity for single adsorbents is challenging but counting for much in adsorptive separations. To this end, a formate metal-organic framework and activated carbon fiber composite was synthesized in our work by a simple two-step process, involving homogeneous precipitation of a MOF precursor on an activated carbon fiber and subsequent template replication. The resultant core-shell composite, ACF@[Ni₃ (HCOO)₆ ], exhibited optimized adsorption performance both in selectivity and capacity for the separation of CH₄ /N₂ to most of state-of-the-art adsorbents.

Keywords: activated carbon fiber; adsorption; core-shell architecture; metal-organic frameworks; template replication.
