With the continuous exploration of low-dimensional nanomaterials, two dimensional metal oxides (2DMOs) has been received great interest. However, their further development is limited by the high cost in the preparation process and the unstable states caused by the polarization of surface chemical bonds. Recently, obtaining mental oxides via liquid metals have been considered a surprising method for obtaining 2DMOs. Therefore, how to scientifically choose different preparation methods to obtain 2DMOs applying in different application scenarios is an ongoing process worth discussing. This review will provide some new opportunities for the rational design of 2DMOs based on liquid metals. Firstly, the surface oxidation process and in situ electrical replacement reaction process of liquid metals are introduced in detail, which provides theoretical basis for realizing functional 2DMOs. Secondly, by simple sticking method, gas injection method and ultrasonic method, 2DMOs can be obtained from liquid metal, the characteristics of each method are introduced in detail. Then, this review provides some prospective new ideas for 2DMOs in other energy-related applications such as photodegradation, CO reduction and battery applications. Finally, the present challenges and future development prospects of 2DMOs applied in liquid metals are presented.
随着对低维纳米材料的不断探索，二维金属氧化物（2DMOs）受到了极大的关注。然而，其进一步的发展受到制备过程成本高和表面化学键极化引起的不稳定状态的限制。最近，通过液态金属获得金属氧化物被认为是获得 2DMOs 的一种令人惊讶的方法。因此，如何科学地选择不同的制备方法，以获得适用于不同应用场景的 2DMOs，是一个值得讨论的持续过程。本综述将为基于液态金属的 2DMOs 的合理设计提供一些新的机会。首先，详细介绍了液态金属的表面氧化过程和原位电取代反应过程，为实现功能 2DMOs 提供了理论基础。其次，通过简单的粘贴法、气体注入法和超声法，可以从液态金属中获得 2DMOs，详细介绍了每种方法的特点。然后，本综述为 2DMOs 在其他与能源相关的应用，如光降解、CO 还原和电池应用中的提供了一些有前景的新想法。最后，提出了 2DMOs 在液态金属中应用所面临的挑战和未来的发展前景。
