Focus topic
CO2 Capture
Scalable hydrophobic MOF composite for energy-efficient humid carbon capture
Summary
Demonstrates high CO2 adsorption capacity (4.6 mmol/g at 298 K, 1 bar), exceptional CO2/N2 IAST selectivity (387), and a low heat of adsorption (Qst = 39.6 kJ/mol).
Shows outstanding moisture stability (water contact angle: 112°) and retains high dynamic CO2 capacity (2.7 mmol/g) and selectivity (284) in breakthrough tests under 85% RH over multiple cycles.
Economically synthesized from low-cost precursors.
What makes this novel compared to best-in-class technology?
Solves the moisture instability of low-cost ALF MOFs while boosting CO2 uptake with a low cost dopant (4.6 mmol/g, CO2/N2 selectivity 387); offers low water binding energy (5.5 kJ/mol) and moderate Qst (39.6 kJ/mol), drastically reducing regeneration energy over amine scrubbing and fluorinated MOFs.
