摘要:	摘要： Efficient hydrogen storage plays a key role in realizing the incoming hydrogen economy. However, it still remains a great challenge to develop hydrogen storage media with high capacity, favourable thermodynamics, fast kinetics, controllable reversibility, long cycle life, low cost and high safety. To achieve this goal, the combination of lightweight materials and nanostructures should offer great opportunities. In this article, we review recent advances in the field of chemical hydrogen storage that couples lightweight materials and nanostructures, focusing on Mg/MgH 2 -based systems. Selective theoretical and experimental studies on Mg/MgH 2 nanostructures are overviewed, with the emphasis on illustrating the influences of nanostructures on the hydrogenation/dehydrogenation mechanisms and hydrogen storage properties such as capacity, thermodynamics and kinetics. In particular, theoretical studies have shown that the thermodynamics of Mg/MgH 2 clusters below 2 nm change more prominently as particle size decreases. Combining lightweight Mg/MgH 2 systems and nanostructures offers the potential to achieve efficient hydrogen storage with improved kinetics and thermodynamics. 其他題名： Chem Commun (Camb) 出版者： England 出版日期： 2012-06-27 出處： Chemical communications (Cambridge, England), 2012-06, Vol.48 (59), p.7334-7343 資源來源： Royal Society of Chemistry 識別號： ISSN: 1359-7345 識別號： ISSN: 1364-548X 識別號： EISSN: 1364-548X 識別號： DOI: 10.1039/c2cc30740e 識別號： PMID: 22715459
