Abstract
A method of capturing carbon dioxide comprising synthesising activated carbon using spent coffee grounds (SCG), polyethylene terephthalate (PET), and potassium hydroxide (KOH). The mixture is co-pyrolyzed at a temperature of less than 500 degrees Celsius activated at a temperature of less than 700 degrees Celsius. Carbon dioxide is adsorbed onto a surface of the synthesized activated carbon at a rate of greater than 8 mmol/g at 0 degrees Celsius and at 1 bar absolute pressure. There is also provided an activated carbon product, wherein the activated carbon product has a carbon dioxide adsorption rate of greater than 8 mmol/g at 0 degrees Celsius and at 1 bar absolute pressure.
