The effect of the conditions of postsynthetic modification of CMK-3 carbon mesoporous molecular sieves on their structural and adsorption properties was studied. The specific surface, volume, pore size, and hydrogen adsorption are markedly enhanced upon activation of CMK-3 by thermal, steam, and chemical treatment using H2, CO2, H2O2, and HNO3. Analysis of the occupancy density of the mesopore surface indicated increased hydrogen adsorption capacity of the hydrogen-activated carbon surface of CMK-3. Hydrogen adsorption is increased from 1.20 to 2.23 mass % at 1 atm and 77 K by steam treatment. This effect may be employed to create efficient carbon MMS adsorbents, including composite adsorbents, for the accumulation and storage of hydrogen at high pressure (adsorption >6 mass %).
