Abstract

Two-dimensional (2D) transition metal borides (MBenes) as an analog to 2D transition metal carbides/nitrides (MXenes) have been considered promising platform materials for exploring their physical and chemical properties, due to their tunable composition, excellent stability, and good conductivity. Lots of theoretical studies have predicted possible mechanical, magnetic, and catalytic properties of MBenes, which inspired their research in energy storage and conversion applications. However, a detailed review focusing on the synthesis of high-quality MBene nanosheets and their energy-related applications is not available. In this review, MBene with different structures and the latest developments in synthesizing high-quality MBene nanosheets from top-down exfoliation and down-top chemical vapor deposition are first summarized. Then, the basic properties of MBene are investigated, including mechanical properties, metallicity, and magnetism. Next, their key applications such as hydrogen production, ammonia production, and energy storage are elaborately discussed. Finally, the future perspectives and key challenges of MBenes's synthesis and applications are briefly provided.

从合成到应用的新兴 MBenes 的最新进展和主要挑战

二维（2D）过渡金属硼化物（MBenes）与二维过渡金属碳化物/氮化物（MXenes）类似，由于其可调整的成分、出色的稳定性和良好的导电性，一直被认为是探索其物理和化学特性的有前途的平台材料。许多理论研究预测了 MBenes 可能具有的机械、磁性和催化特性，这激发了人们对其在能量存储和转换应用方面的研究。然而，关于高质量 MBene 纳米片的合成及其能源相关应用的详细综述还没有。本综述首先概述了不同结构的 MBene 以及通过自上而下剥离和自下而上化学气相沉积合成高质量 MBene 纳米片的最新进展。然后，研究了 MBene 的基本特性，包括机械特性、金属性和磁性。接着，详细讨论了它们的主要应用，如制氢、制氨和储能。最后，简要介绍了美贝烯合成和应用的未来前景和主要挑战。
