Direct Air Capture using COF-992
Researchers at the University of California, Berkeley, USA, have developed a new porous material that efficiently captures CO₂ from ambient air without degradation.
DAC (Direct Air Capture) The porous material COF-999 — a covalent organic framework (COF) — captures CO2 from ambient air without degradation by water or other contaminants, one of the limitations of existing DAC technologies.
The new material could be substituted easily into carbon capture systems already deployed or being piloted to remove CO2 from refinery emissions and capture atmospheric CO2 for storage underground.
UC Berkeley graduate student Zihui Zhou, the paper’s first author, said that a mere 200 grams of the material, a bit less than half a pound, can take up as much CO2 in a year — 20 kilograms (44 pounds) — as a tree.
