A hydrophobic CO 2 physisorbent Most materials for carbon dioxide (CO ) 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 . Lin et al show zinc-based metal organic framework material physisorb and incurs lower regeneration penalty. Its binding site at the center pores precludes formation hydrogen-bonding networks between water molecules.

Global climate change ensued by the rise in atmospheric CO2 levels is one of greatest challenges our planet facing today. This worldwide distress demands technologies that can contribute to society toward "negative carbon emissions". Carbon capture and storage (CCS) are important role for capturing from existing emission sources, such as industrial energy production point before new more prominent modifications infrastructure be implemented. Recently, alongside source capture, direct air (DAC) processes have emerged highly sought-after able ambient air. Alongside traditional inorganic adsorbents, a class solid porous called metal-organic frameworks (MOFs) recent years also, group potentially very efficient materials CO2.
