| 摘 要： | 利用容积法测量了77K下氢在一种碳纳米纤维上的吸附等温线。采用分子模拟的方法模拟了77K下氢分子在平板状碳纳米纤维中的吸附,碳纳米纤维的石墨层层间距分别为0.335nm、0.6nm、0.9nm以及1.5nm。模拟结果表明:石墨层层间距为0.335nm的碳纳米纤维在77K下吸附储氢密度很难达到DOE的能量密度标准;当板间距为0.9nm时,系统吸附储氢的重量密度和体积密度均能达到最大,且在77K、1MPa下,能达到DOE的能量密度标准。

| Abstract: | The volumetric method has been used to obtain the adsorption isotherm of gas phase hydrogen in one nanofiber at 77K.Hydrogen adsorption in platelet carbon nanofiber has been simulated with molecular simulation method at 77K,which pore width were respectively 0.335nm,0.6nm,0.9nm and 1.5nm.The simulated results show that the uptake of hydrogen in carbon nanofiber that pore width is 0.335nm hardly meet the energy density standard of DOE at low temperature.When pore width is 0.9nm,both hydrogen storage weight density and volumetric density come to a head,and at 77K and 1MPa both can meet the energy density standard of DOE. |
