Abstract:
The present application relates to absorbents comprising tetraamine ligands grafted onto metal-organic frameworks and a method for using same for CO2 capture from fossil fuel combustion sources to reduce emissions. In particular, this application relates to capturing >90% by volume, preferable >99% by volume, CO2 emissions such that the emissions are negative, essentially removing CO2 from the combustion air.
