Design of Ultra-Stable Solid Amine Adsorbents and Mechanisms of Hydroxyl Group-Dependent Deactivation for Reversible CO2 Capture from Flue Gas

Design of Ultra-Stable Solid Amine Adsorbents and Mechanisms of Hydroxyl Group-Dependent Deactivation for Reversible CO2 Capture from Flue Gas

Highlights We reveal that the nature of the hydrogen bonding networks formed by surface hydroxyl groups plays a key role in the deactivation mechanisms of supported polyethylenimine (PEI), which exhibits contrasting oxidative and anti-urea properties when supported on Al–OH- and Si–OH-containing sub...
