The specific surface areas and total pore volumes of ZnxCoy–C/CNT composites were calculated by using the Brunauer–Emmett–Teller (BET) model. Note that the pore structure of the ZnxCoy–C/CNT composites is highly dependent on

Conclusion In summary, we have extended the FEBID continuum model beyond Langmuir adsorption, allowing for adsorbate coverages above one monolayer. We have used the approach followed by the BET model, introducing two
