Résumé

The hydrogen adsorption by carbon nanofibres has been experimentally studied together with computer simulations. Adsorption isotherms on one kind of carbon nanofibres have been volumetrically measured over a temperature range of 273-353 K. The adsorption amount is small. And the adsorption and desorption isotherms are almost reversible, which reveals the characteristics of physisorption. Grand canonical ensemble Monte Carlo approach is also used to simulate hydrogen adsorption on carbon nanofibres with different pore width. Simulated results show that it is difficult to meet the DOE target (6.4 wt%, 62.0 m3/kg) when the pore width is 0.34 nm. When the pore width is expanded to 0.9 nm, the hydrogen uptake reaches a maximum at a moderate pressure, and can meet the target under 1 MPa at 77 K. The potential energy theory is also adopted to explain the simulation results.
