A scalable metal-organic framework as a durable physisorbent for carbon dioxide capture

A hydrophobic CO 2 physisorbent Most materials for carbon dioxide (CO 2 ) capture of fossil fuel combustion, such as amines, rely on strong chemisorption interactions that are highly selective but can incur a large energy penalty to release CO 2 . Its binding site at the center of the pores precludes the formation of hydrogen-bonding networks between water molecules.

• 1 show that a zinc-based metal organic framework material can physisorb CO 2 and incurs a lower regeneration penalty.
• 2 Its binding site at the center of the pores precludes the formation of hydrogen-bonding networks between water molecules.
• 3 This durable material can preferentially adsorb CO2 at 40% relative humidity and maintains its performance under flue gas conditions of 150°C.
