  • metal oxides for the adsorption of CO 2 represents a considerable technological advantage. Since the adsorption process takes place at the surface level, a fundamental parameter that regulates the effectiveness in the practice of the CO 2 adsorption process is the specific area of contact between the gas and the metal oxide in the solid state. Certain adsorbent metal oxides that are obtained from natural precursors are characterized by having a very large amount of micropores (pores smaller than 2 nanometers).
