摘要：采用容量法研究温度在273～300K范围内,压力升高到10 MPa时多壁碳纳米管的吸附储氢性能。采用SEM、TEM和低温N_2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9.1 kJ/mol。
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 rnierostruetures were characterized by scanning electron microscopy （SEM）, transmission electron microcopy （TEM）, N2 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. Isosterie heat of adsorption was evaluated from a set of isotherms basing on the Clausius- Clapeyron equation, and 9.1 kJ/mol was obtained for MWNT.
