Carbon dioxide adsorption on activated carbon hydrothermally treated andimpregnated with metal oxides

Activated carbon (AC) has been used widely as an agent for carbon dioxide (CO2) adsorption due to its environmentally friendly nature, low cost, high porous structure, high surface area and good mechanical properties. Modifications have been made to AC in order to enhance its adsorptive properties....
