A new type of porous material called a covalent organic framework quickly sucks up carbon dioxide from ambient air. It has hexagonal channels decorated with polyamines that efficiently bind CO2 molecules (blue and orange balls) at concentrations found in ambient air without degradation by water or other contaminants. It 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. A mere 200 grams of the material, a bit less than half a pound, can take up as much CO2 in a year (44 pounds) as a tree.
