摘 要: 介绍了新能源战略下储氢材料的发展,其中单壁碳纳米管和碱金属掺杂的碳富勒烯具有很好的应用前景。最近的研究表明:纳米管的最大氢化度依赖于其直径,直径约为2.0 nm的单壁碳纳米管-氢复合物具有100%的氢化度和通过可逆碳-氢键的形成而达7%以上的质量比储氢容量,而用钠原子掺杂的碳富勒烯的储氢容量高达9.5%,并且在室温下稳定。
关 键 词: 能源与节能;储氢材料;单壁碳纳米管;钠原子掺杂的碳富勒烯;重量比储氢容量;化学吸附

Abstract: This paper introduces the development of materials for hydrogen storage under new energy stratagem. Both the single-walled carbon nanotubes and the alkali metal doped fullerene (C60) have excellent application prospect. The recent results show that the maximal hydrogenation degree of nanotube depends on the nanotube diameter and the single-walled carbon nanotube-hydrogen composite with diameter value around 2.0 nm have almost 100% hydrogenation degree and a hydrogen storage capacity higher than 7 wt% due to formation of reversible carbon-hydrogen bonds, while the hydrogen storage capacity of the sodium atom doped fullerene is up to 9.5 wt% and is stable at room temperature.
Key words: energy and energy saving; materials for hydrogen storage; single-walled carbon nanotubes; sodium atom doped fullerene; hydrogen storage capacity; chemisorption
