文摘

Amine-grafted porous polymer networks were investigated for CO₂ capture directly from air (400 ppm CO₂, 78.96% N₂, and 21% O₂). Under these ultradilute conditions, PPN-6-CH₂DETA has an extraordinarily high CO₂ selectivity (3.6 脳 10p>10p>) and loading capacity (1.04 mol/kg) as calculated using ideal adsorption solution theory. In addition we have shown that the material outperforms other materials based on simulated breakthrough calculations, thus showing great potential to be used in direct air capture applications.
