摘要:
The hydrogen adsorption capacities of several activated carbon were determined in relation with their texture characteristics. Nitrogen adsorption isotherms were used for determining the total volume of micropores. The total surface area and micropore volume were determined by physical adsorption of nitrogen at 77 K and CO2 at 273 K, respectively. The characterization by CO2 adsorption allows to assess the information of prime importance for the case of hydrogen storage applications.
