ADSORPTION OF HYDROGEN IN DIFFERENT STRUCTURAL SINGLE-WALLED CARBON NANOTUBE ARRAYS
The adsorption of hydrogen in square and triangular single walled carbon nanotube arrays was studied with grand canonical ensemble Monte Carlo method The adsorption isotherm was simulated at 77 K , 133 K and 298 K, and the ability of hydrogen adsorption storage in two different structural SWNTA was compared The reason for the difference in adsorption ability of the two SWNTA was analyzed according to potential field distribution, and the potential field distribution of different tube diameters and different inter tube spacings and the effect of potential field distribution on adsorption ability were discussed.The inter tube spacing is the key factor inducing the difference of potential field distribution and adsorption ability of different structural nanotube arrays.
