| 摘 要： | 采用容量法研究温度在273～300K范围内,压力升高到10MPa时多壁碳纳米管的吸附储氢性能.采用SEM、 TEM和低温N2吸附对碳纳米管的微观结构进行表征.结果发现,在相同压力下吸附量随温度的增加而降低,表明碳纳米管的吸附主要是物理吸附.采用Clausius-Clapeyron方程解析了氢气在碳纳米管上的等量吸附热,平均值为9.1kJ/mol.

| Abstract: | Adsorption storage of hydrogen on multi-walled carbon nanotubes (MWNT) were investigated using volumetric method for the range of 273-300 K and pressures up to 10 MPa.MWNTs microstructures were characterized by scanning electron microscopy (SEM),transmission electron microcopy (TEM),N_2 adsorption in low temperature.At the same equilibrium pressure,the hydrogen adsorption of carbon nanotubes decreased with the temperature increasing,which is typical for physical adsorption.Isosteric heat of adsorption was e... |
