摘要：研究了不同直径的多壁碳纳米管对其吸附储氢的影响。其中的碳纳米管以Fe/SiO2粉状物作催化剂分别在600、700、800℃下用化学沉积法制备。结果发现,碳纳米管粗样品储氢量很少,而纯化后的样品的储氢量有了明显的提高。同时碳纳米管的储氢量与其直径存有一定的比例关系,这表明碳纳米管的直径对储氢量产生很大的影响。
The influence of multi-walled carbon nanotubes （MWNTs） with different diameters on hgdrogen adsorption storage was investigated. The MWNTs were synthesized by chemical vapor deposition （CVD） using iron nanoparticles embedded in mesoporous silica as catalyst and were treated in vacuum at different temperature of 600, 700 and 800℃. It was found that the as-grown carbon nanotubes had poor hydrogen up-take capacity at room temperature under modest pressure （10MPa）, however, the hydrogen storage amount was improved remarkably in the purified and pretreated MWNTs. Further, the hydrogen storage capacity of the purified MWNTs was proportional to their diameter. This showes that the diameter of MWNTs is an important factor that influences its hydrogen adsorption storage performance.
