Top five in CO2 capture capacity*:
1. COP-1: 5616 mg/g
2. MOF-210: 2870 mg/g
3. NU-100: 2315 mg/g
4. PPN-4: 2121 mg/g
5. COP-2: 2086 mg/g
*These capacities reflect the highest recorded values, regardless of the conditions. In addition, according to our recent high pressure data on common solids, we believe the rankings won't change much even if the pressures are raised.

With 5616 mg/g, COP-1 sets the new world record for the highest CO2 capture capacity
At infinite selectivity, COP-2 holds the world record in CO2/H2 separation
Efficient CO2 scrubbing without
a significant energy penalty remains an outstanding challenge for fossil fuel-burning
industry where aqueous amine solutions are still widely used. Porous materials
have long been evaluated for next generation CO2 adsorbents. Porous
polymers, robust and inexpensive, show promise as feasible materials for the
capture of CO2 from warm exhaust fumes. We report the syntheses of
porous covalent organic polymers (COPs) with CO2 adsorption
capacities of up to 5616 mg/g (measured at high pressures, i.e.200 bar) and
industrially relevant temperatures (as warm as 65 oC). COPs are stable
in boiling water for at least one week and near infinite CO2/H2
selectivity is observed.
