The hybrid ultraporous material TIFSIX-Ni ([Ni(pyrazine)2(TiF6)]n) was incorporated into a composite ink for the first time three-dimensional (3D) printing of monoliths. large-scale synthesis completed using two different Ni(II) salts, with CO2 uptakes 1.90 mmol g-1 achieved mechanochemically assisted thermal synthesis. monoliths were then tested capture and release gas electric swing adsorption (ESA) under dry humid conditions. A working capacity 1.7% (comparing dynamic data isotherm data) when current 2.1 applied 10 min. monolith could be cycled repeatedly 6 h without impacting performance or loss capacity. Part this work explored improvement synthetic methods TIFISX-Ni in reducing costs associated production, allowing improvements overall scale-up processability industrial applications.
