| 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. |
