Abstract

Borophene, a two-dimensional allotrope of boron, has emerged as a promising material for gas sensing because of its exceptional electronic properties and high surface reactivity. This review comprehensively overviews borophene synthesis methods, properties, and sensing applications. However, it is crucial to acknowledge the substantial gap between the abundance of theoretical literature and the limited experimental studies. While theoretical investigations have elucidated the stability and remarkable sensing capabilities of various borophene polymorphs across different gases, significant experimental challenges have hindered the translation of these theoretical predictions into practical devices. Consequently, this review carefully studies these challenges and shortcomings that are jeopardizing the practical implementation of borophene in real-world settings. Specifically, four key issues are thoroughly studied, such as superficial borophene oxidation upon exposure to the air, interference from relative humidity on gas molecule detection, lack of selectivity, and synthesis scalability. Finally, novel strategies are proposed to overcome these bottlenecks. By adopting these approaches, borophene can pave the way to drive the advancement of the next generation of sensing devices.

波罗芬气体传感器路线图
硼苯是硼的一种二维同素异形体,由于其特殊的电子特性和高表面反应性,已成为一种很有前途的气体传感材料。本文综述了硼苯的合成方法、性质及其传感应用。然而,认识到丰富的理论文献与有限的实验研究之间的巨大差距是至关重要的。虽然理论研究已经阐明了各种硼罗芬多晶在不同气体中的稳定性和卓越的传感能力,但重大的实验挑战阻碍了这些理论预测转化为实际设备。因此,本综述仔细研究了这些挑战和缺点,这些挑战和缺点危及波罗芬在现实环境中的实际应用。具体来说,我们深入研究了四个关键问题,如暴露在空气中的表面波罗芬氧化,相对湿度对气体分子检测的干扰,缺乏选择性和合成可扩展性。最后,提出了克服这些瓶颈的新策略。通过采用这些方法,borophene可以为推动下一代传感设备的进步铺平道路。

期刊介绍: ACS Sensors is a peer-reviewed research journal that focuses on the dissemination of new and original knowledge in the field of sensor science, particularly those that selectively sense chemical or biological species or processes. The journal covers a broad range of topics, including but not limited to biosensors, chemical sensors, gas sensors, intracellular sensors, single molecule sensors, cell chips, and microfluidic devices. It aims to publish articles that address conceptual advances in sensing technology applicable to various types of analytes or application papers that report on the use of existing sensing concepts in new ways or for new analytes.
