摘要

由于缺乏适当的储氢方法,氢无法作为一种主要能源加以利用。由于石墨烯具有高比表面积,因此石墨烯基材料已被考虑用作固体储氢材料。然而,这些材料本身并不符合美国能源部(DOE)规定的 6.5 wt.% 的储氢标准。不过,通过装饰或掺杂,可以很容易地改变它们的化学特性,提高储氢能力。本综述汇编了已发表的有关该主题的各种报告,并总结了探索金属改性石墨烯材料储氢特性的理论和实验研究结果。研究考察了碱金属、碱土金属和过渡金属装饰的功效。此外,还考虑了掺杂金属以进一步提高储氢能力的问题。随后还解释了储氢容量测量方法,并总结了有效储氢材料的特性。

Hydrogen Storage Properties of Metal-Modified Graphene Materials
The absence of adequate methods for hydrogen storage has prevented the implementation of hydrogen as a major source of energy. Graphene-based materials have been considered for use as solid hydrogen storage, because of graphene’s high specific surface area. However, these materials alone do not meet the hydrogen storage standard of 6.5 wt.% set by the United States Department of Energy (DOE). They can, however, be easily modified through either decoration or doping to alter their chemical properties and increase their hydrogen storage capacity. This review is a compilation of various published reports on this topic and summarizes results from theoretical and experimental studies that explore the hydrogen storage properties of metal-modified graphene materials. The efficacy of alkali, alkaline earth metal, and transition metal decoration is examined. In addition, metal doping to further increase storage capacity is considered. Methods for hydrogen storage capacity measurements are later explained and the properties of an effective hydrogen storage material are summarized.
