镁基复合储氢材料的研究进展

Progress of Research on Magnesium-based Hydrogen Storage Composites

金属镁具有储氢密度大、价格低廉、资源丰富等优点,是当前最有发展前景的储氢材料之一,但其动力学性能差,需要高温才能吸收和放出氢气。为了改善其储氢性能,除制备镁基合金外,利用机械球磨法制备镁基复合储氢材料也得到了广泛研究。对目前制备的镁基复合储氢材料进行了分类,并分别介绍了各类的研究进展。

Mg is believed to be one of the most promising solid hydrogen storage materials because of its advantages such as large hydrogen capacity, low cost, natural abundance, et al. Besides magnesium-based metal alloys, magnesium-based hydrogen storage composites fabricated by mechanical ball milling have also been researched to improve its hydrogen storage performances. The classification and the research progress of the magnesium-based hydrogen storage composites are reviewed.
