When 'too good to be true' means what it says
@ZgroupUL has had many 'too good to be true' events over 37 yrs.🇮🇪🇨🇦🇺🇸 Some, (ionic liquids, ultramicroporous physisorbents, pharmaceutical cocrystals) are the real deal + general in nature. Most were not.

Theoretical chemists Theoretical Chemistry Group (Chuo Univ., Tokyo) and chemical engineers at Nihon Univ. collaborated with Kanazawa Univ. & RITE to establish an optimization protocol of CO2 physisorbents based on electronic structure informatics & precision measurements.

David Paul Iacomi @lscottblank Marco Taddei ....main issue with amines can be deactivation in the presence of oxygen. NbOFFIVE-1-Ni and SGU-29 are the leaders here for physisorbents. SGU-29 edging it as it has specific binding sites for CO2 and H2O, which overcomes coadsorption issues. SIFSIX-18-Ni good too Soumya Mukherjee
David Paul Iacomi @lscottblank Isotherms for amine modified materials have very steep uptake at low pressures. The kinetics at low partial pressures however is a bit slower than physisorbents but as Marco Taddei mentioned water has little effect and can be beneficial....
David Paul Iacomi @lscottblank To the best of my knowledge, there are only a handful of physisorbents that can capture appreciable amounts of CO2 at 400 ppm: SIFSIX-3-Cu, NbOFFIVE-1-Ni (both MOFs) and SGU-29 (a copper silicate). They have Qst in the region of 50-60 kJ/mol, so are rather strong physisorbents.
