Magnetic field‐assisted concentration swing adsorption for CO 2 capture over Fe 3 O 4 /fibrous nanosilica‐PEI adsorbent
Abstract
Abstract Magnetic field‐assisted concentration swing adsorption (CSA) provides an electrification‐compatible alternative to conventional temperature swing adsorption (TSA) by enabling rapid heating/cooling and energy‐efficient regeneration under near‐isothermal conditions, thereby eliminating the need for sensible heat input. Here, Fe 3 O 4 nanoparticles were integrated with fibrous nanosilica (FNS) and polyethylenimine (PEI) to construct a magnetically responsive adsorbent for near‐isothermal CSA of CO 2 . Benefiting from the radially fibrous pore structure of FNS, Fe 3 O 4 /FNS‐PEI70 exhibited fast adsorption kinetics (
