Study on the Preparation and CO2 Adsorption Performance of Carbon material

Abstract

Carbon materials are valuable for adsorbing CO2. In this work, carbon materials with large specific surface area and pore volume were prepared through the combination of sodium alginate and zinc chloride, were applied to adsorb CO2 at 273 K and 298 K, showing a large adsorption capacity 2.75 mmol g-1 and 2.19 mmol g-1, respectively. Zinc chloride acts as an activator and pore forming agent.
