Background:

  • Hydrogen adsorption on carbon materials is crucial for energy storage applications.
  • Understanding the influence of carbon properties on hydrogen uptake is vital.

Purpose of the Study:

  • To systematically investigate the impact of functional groups and porous structure on hydrogen adsorption in porous carbons.
  • To determine the thermodynamic properties of hydrogen adsorption and their relation to storage limitations.

Main Methods:

  • Preparation of porous carbons with varying nitrogen and oxygen functional groups.
  • Characterization of porous structures using nitrogen and carbon dioxide adsorption.
  • Measurement of hydrogen adsorption isotherms at 77 K and 100 kPa.

  • Determination of adsorption enthalpies using virial and van't Hoff equations.

    • Main Results:

    • Hydrogen adsorption isotherms were Type I (IUPAC classification).
    • Adsorption is highly temperature-dependent, with minimal uptake above 195 K.
    • Isosteric enthalpies of adsorption ranged from 3.9-5.2 kJ mol⁻¹.
    • Maximum hydrogen uptake correlated with micropore volume.

    Conclusions:

    • Porous carbon structure, particularly micropore volume, is key for hydrogen adsorption capacity.
    • Functional groups have a minor negative effect on hydrogen adsorption.
    • Thermodynamics indicate significant temperature limitations for practical hydrogen storage.
