Abstract
A method of capturing CO2 and converting the captured CO2 into useful byproducts includes providing a material including a material matrix holding an ionic liquid, exposing the material to a source of thermal energy to capture CO2 within the material, removing the material from exposure to the source of thermal energy, and washing the material with a solution to convert the captured CO2 and wash the converted, captured CO2 from the material as filtrate. Materials and systems for capturing CO2 and converting the captured CO2 into useful byproducts are also provided.
