| 摘 要： | 研究了单壁碳纳米管(SWNTs)干法储氢和碳纳米管(SWNTs)-四氢呋喃(THF)水合物法储氢的过程. 结果表明, 实验所用的SWNTs在16.5 MPa压力下, 温度为0.5 ℃时, 氢气的吸附存储量为0.75%(质量分数), 经浓酸处理后, 氢气的存储量可以达到1.15%, SWNTs-THF水合物法储氢量为0.37%, 与碳纳米管干法储氢相比, 储氢量有所降低.

| Abstract: | Hydrogen absorption capability of three types of samples(dry SWNTs before and after concentrated acid treatment,and THF solution absorbed SWNTs) were compared.The results indicate that when temperature is 0.5 ℃ and pressure is 16.5 MPa,the hydrogen gas absorption rate of dry SWNTs before and after concentrated acid treatment are 0.75% and 1.15%(mass fraction),respectively.Hydrogen absorption rate of THF solution absorbed SWNTs is about 0.37%(mass fraction),lower than that of dry SWNTs because of the formation of THF hydrate. |
