Abstract：
As an environmentally friendly and high-density energy carrier, hydrogen has been recognized as one of the ideal alternatives for fossil fuels. One of the major challenges faced by \"hydrogen economy\" is the development of efficient, low-cost, safe and selective hydrogen generation from chemical storage materials. In this review, we summarize the recent advances in hydrogen production via hydrolysis and alcoholysis of light-metal-based materials, such as borohydrides, Mg-based and Al-based materials, and the highly efficient regeneration of borohydrides. Unfortunately, most of these hydrolysable materials are still plagued by sluggish kinetics and low hydrogen yield. While a number of strategies including catalysis, alloying, solution modification, and ball milling have been developed to overcome these drawbacks, the high costs required for the \"one-pass\" utilization of hydrolysis/alcoholysis systems have ultimately made these techniques almost impossible for practical large-scale applications. Therefore, it is imperative to develop low-cost material systems based on abundant resources and effective recycling technologies of spent fuels for efficient transport, production and storage of hydrogen in a fuel cell-based hydrogen economy.
摘要：
作为一种环保、高密度的能源载体,氢已被公认为化石燃料的理想替代品之一。“氢经济”面临的主要挑战之一是发展高效、低成本,从化学储存材料中安全和选择性地产生氢气。在这次审查中,我们总结了轻金属基材料水解和醇解制氢的最新进展，如硼氢化物，镁基和铝基材料，以及硼氢化物的高效再生。不幸的是,这些可水解材料中的大多数仍然受到缓慢的动力学和低氢产率的困扰。虽然包括催化在内的许多策略，合金化，解决方案修改，和球磨已经被开发来克服这些缺点，水解/醇解系统的“单程”利用所需的高成本最终使这些技术几乎不可能用于实际的大规模应用。因此,必须开发基于丰富资源和有效回收乏燃料技术的低成本材料系统，以实现高效运输，在基于燃料电池的氢经济中生产和储存氢。
