A hydrophobic CO<sub>2</sub>physisorbent Most materials for carbon dioxide (CO2) 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 CO2. Linet al. show that a zinc-based metal organic framework material can physisorb CO2and incurs a lower regeneration penalty. Its binding site at the center of the pores precludes the formation of hydrogen-bonding networks between water molecules. This durable material can preferentially adsorb CO2 at 40% relative humidity and maintains its performance under flue gas conditions of 150°C. —PDS
