碳纳米管贮氢研究进展

Advance in Hydrogen Storage of Carbon Nanotubes

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。

The advance in experiment and theory research of hydrogen storage in carbon nanotubes(CNTs)was reviewed in this paper. The results of experiments obtained by different researchers were much inconsistent such as from 67(wt)% to 0.01(wt)%.However, the results of theory simulation were less inconsistent. It was regarded that hydrogen adsorbed in CNTs was affected strongly by effective surface areas therefore the geometric piled shape of single-walled CNTs also played an important role in hydrogen adsorption. Many rsearchers reegarded that CNTs was not a good H 2-storage material,of which its capacity was less than 1(wt)%.
