Magnesium (Mg) has many unique properties suitable for applications in the fields of energy conversion and storage. These fields presently rely on noble metals for efficient performance. However, among other challenges, noble metals have low natural abundance, which undermines their sustainability. Mg has a high negative standard reduction potential and a unique crystal structure, and its low melting point at 650 °C makes it a good candidate to replace or supplement numerous other metals in various energy applications. These attractive features are particularly helpful for improving the properties and limits of materials in energy systems. However, knowledge of Mg and its practical uses is still limited, despite recent studies which have reported Mg's key roles in synthesizing new structures and modifying the chemical properties of materials. At present, information about Mg chemistry has been rather scattered without any organized report. The present review highlights the chemistry of Mg and its uses in energy applications such as electrocatalysis, photocatalysis, and secondary batteries, among others. Future perspectives on the development of Mg-based materials are further discussed to identify the challenges that need to be addressed.
镁 (Mg) 具有许多独特的性质，适合应用于能量转换和存储领域。这些领域目前依赖于贵金属以实现高效性能。然而，除其他挑战外，贵金属的自然丰度低，这损害了它们的可持续性。Mg 具有高的标准还原电位和独特的晶体结构，其 650°C 的低熔点使其成为在各种能源应用中替代或补充许多其他金属的良好候选材料。这些吸引人的特性对于改善能源系统中材料的性能和限制特别有帮助。然而，尽管最近的研究报告了 Mg 在合成新材料结构和修饰材料化学性质方面的关键作用，但对 Mg 及其实际用途的了解仍然有限。目前，有关 Mg 化学的信息相当分散，没有任何有组织的报告。本综述重点介绍了 Mg 的化学性质及其在电催化、光催化和二次电池等能源应用中的用途。进一步讨论了对基于 Mg 的材料的发展的未来展望，以确定需要解决的挑战。
