In an effort to realize a sustainable hydrogen economy, we are facing the demanding and challenging issue of providing compact and safe storage solutions for hydrogen in solid-state materials. Studies on the hydrogen storage properties of materials generally involve their phase structures, microstructures, thermal/structural stability, chemical compositions and bonding, which can be studied by ex situ experimental technologies. However, the experimental results obtained from ex situ measurements may be contaminated during sample handling, and some important intermediate phases are too metastable/unstable to be detected. To overcome the drawbacks, in situ studies are carried out, leading to a large number of unprecedented advantages. In this review, recent advances regarding in situ measurement technologies for solid-state hydrogen storage materials are summarized, mainly focusing on metal hydrides and complex hydrides. The working principles together with the devices used for the in situ methods are briefly introduced. Afterwards, both the classic and recent advances regarding the in situ measurement technologies for metal hydrides and complex hydrides are comprehensively summarized and reviewed. In addition to highlighting the tremendous merits of the in situ methods and the relevant achievements in the field of hydrogen storage materials, the remaining challenges and trends of the emerging research are also discussed.

固态储氢材料的原位测量技术

为了实现可持续的氢经济,我们面临着为固态材料中的氢提供紧凑安全的存储解决方案的艰巨挑战。材料储氢性能的研究通常涉及它们的相结构,微观结构,热/结构稳定性,化学组成和键合,可以通过异位实验技术进行研究。但是,从异地测量获得的实验结果可能会在样品处理过程中受到污染,并且某些重要的中间相太亚稳/不稳定,无法被检测到。克服缺点,就地进行了研究,从而带来了许多前所未有的优势。在这篇综述中,总结了有关固态储氢材料现场测量技术的最新进展,主要集中在金属氢化物和复合氢化物上。简要介绍了工作原理以及用于现场方法的设备。随后,对金属氢化物和复杂氢化物的现场测量技术的经典和最新进展进行了全面总结和回顾。除了强调原位的巨大优点 方法和储氢材料领域的相关成就,还讨论了新兴研究的剩余挑战和趋势。
