Abstract:Functional groups on the surface chemical and pore structure are the main properties in the performance of activated carbon adsorption. Coal-based activated carbon product is used as a precursor to clarify that the oxygen-blowing into precursor structure can form new site oxygen-containing on the surface. Oxygen functional groups are verified through calcination under a nitrogen atmosphere. The process of oxygen-blowing is conducted at different temperatures of 100, 200, 300, 400, and 500°C and calcination at … Show more
