综述了碳纳米管在实验和理论方面的贮氢研究工作。不同科研工作者得到的实验结果很不一致 ,重量百分比分布在 6 7%～ 0 0 1 %之间 ,理论模拟结果差别相对小一些。碳纳米管中的氢吸附受有效表面积和孔体积的强烈影响 ,单壁碳纳米管堆积的几何形状在氢吸附中也起着重要作用。不少研究者认为碳纳米管并不是适合的贮氢材料 ,其贮氢量在 1 (wt) %以下。
In this paper, the hydrogen storage of carbon nanotubes in experimental and theoretical studies is reviewed. The experimental results obtained by different researchers are very inconsistent, with weight percentages ranging from 67% to 0% and theoretical differences in the simulation results being relatively small. Hydrogen adsorption in carbon nanotubes is strongly influenced by the effective surface area and pore volume, and the geometry of single-walled carbon nanotubes stacking also plays an important role in hydrogen adsorption. Many researchers believe that carbon nanotubes are not suitable hydrogen storage materials, the hydrogen storage capacity of 1 (wt)% or less.
