Abstract

Abstract: Porous polymer networks (PPNs) is an emerging category of advanced porous materials that are of interest for carbon capture due to their high physicochemical stability and convenient functionalization process. Herein, a series of alkylamine tethered PPN-200 (PPN-200-DETA, PPN-200-TETA and PPN-200-TAEA) were prepared through a novel post-synthetic strategy. Due to the presence of alkylamine groups, PPN-200-TAEA has CO2 uptakes of 42 cm 3 /g (at 298 K and 0.15 bar) and 55 cm 3 /g (at 298 K and 1 bar), and a calculated CO2 /N2 selectivity of 289, which demonstrate its potential in postcombustion carbon capture application. Graphical abstract: Highlights: A novel strategy was designed to construct alkylamine tethered PPNs, which demonstrated high CO2 uptake. Among them, the CO2 uptake of PPN-200-TAEA reaches 42 cm 3 /g (8.3 wt%) and its calculated CO2 /N2 selectivity reaches 289. Given the outstanding stability and high CO2 adsorption, the PPN-200-TAEA has great potential in post-combustion carbon capture.
