Amine-containing solids are promising adsorbents for CO2 capture, but their low oxidative stability has hindered their application. Here, Choi and colleagues develop a strategy to poison the metal impurities present in poly(ethyleneimine)/silica adsorbents, significantly improving their stability towards oxidation.
