摘　　要：作为一种新型的清洁能源,氢能在日益严峻的能源危机中越来越重要。纳米储氢合金因其优异的性能,被认为是下一代重要的储氢材料。本文介绍了储氢合金的原理、储氢合金的动力学和热力学以及各种储氢材料性能。基于储氢合金的最新研究进展,本文综述了提高纳米合金储氢性能的措施、纳米储氢合金的制备方法及其优缺点,进一步探讨了影响纳米合金储氢性能的因素,对储氢合金的进一步发展进行了展望。Hydrogen energy,as a new kind of clean energy,is getting increasingly important in the energy crisis in recent decades.Nanoalloys show great foreground because of their extraordinary properties in different fields of subjects.The hydrogen storage nanoalloys have been regarded as one of the most important hydrogen storage materials.In this review,we introduce the principle of the hydrogen storage nanoalloys and properties of different kinds of hydrogen storage materials,which offer guidance from the point of view of thermodynamics and kinetics.Three methods to improve the hydrogen storage are discussed,namely alloying,non-crystallizing,and nanocrystallization.Then several preparation methods of hydrogen storage nanoalloys are reviewed with brief introduction of their advantages and disadvantages,where we pay more attention to the three methods,i.e.,the mechanical disintegration/alloying,gaseous coacervation and cluster beam deposition.Furthermore,the factors affecting the properties of hydrogen storage alloy,such as structure,component and size,are discussed.In the end,we prospect the future of hydrogen storage materials.
