Manganese dioxide (MnO) nanomaterials have shown excellent performance in catalytic degradation and other fields because of their low density and great specific surface area, as well as their tunable chemical characteristics. However, the methods used to synthesize MnO nanomaterials greatly affect their structures and properties. Therefore, the present work systematically illustrates common synthetic routes and their advantages and disadvantages, as well as examining research progress relating to electrochemical applications. In contrast to previous reviews, this review summarizes approaches for preparing MnO nanoparticles and describes their respective merits, demerits, and limitations. The aim is to help readers better select appropriate preparation methods for MnO nanomaterials and translate research results into practical applications. Finally, we also point out that despite the significant progress that has been made in the development of MnO nanomaterials for electrochemical applications, the related research remains in the early stages, and the focus of future research should be placed on the development of green synthesis methods, as well as the composition and modification of MnO nanoparticles with other materials.
二氧化锰（MnO）纳米材料因其低密度、大比表面积以及可调节的化学特性，在催化降解等领域展现出优异性能。然而，用于合成MnO纳米材料的方法极大地影响其结构和性能。因此，本工作系统阐述了常见的合成路线及其优缺点，并考察了与电化学应用相关的研究进展。与以往综述不同，本综述总结了制备MnO纳米颗粒的方法，并描述了它们各自的优缺点及局限性。目的是帮助读者更好地为MnO纳米材料选择合适的制备方法，并将研究成果转化为实际应用。最后，我们还指出，尽管在用于电化学应用的MnO纳米材料开发方面已取得显著进展，但相关研究仍处于早期阶段，未来研究重点应放在绿色合成方法的开发以及MnO纳米颗粒与其他材料的复合和改性上。
