Description
Plant waste may help trap carbon dioxide, and a 2026 simulation study by Mohsen Samandari, David P. Harper, and David J. Keffer tests lignin-based materials on the computer. Cheap, benign sorbents are wanted for carbon capture, and lignin, a byproduct of paper and biofuel making, is plentiful.
The team simulated tiny carbon dots with four kinds of surface chemistry, placed on graphite and on a lignin-derived carbon base. All dot types preferred carbon dioxide over nitrogen and oxygen, with strength varying by chemistry and coverage. The bare lignin base alone proved strikingly selective, favoring carbon dioxide more than fiftyfold in dry and wet flue gas. Adding dots raised capacity without costing that selectivity in dry gas.
