The intrinsic and electronic properties of elemental two-dimensional (2D) materials beyond graphene are first introduced in this review. Then the studies concerning the application of gas sensing using these 2D materials are comprehensively reviewed. On the whole, the carbon-, nitrogen-, and sulfur-based gases could be effectively detected by using most of them. For the sensing of organic vapors, the borophene, phosphorene, and arsenene may perform it well. Moreover, the G-series nerve agents might be efficiently monitored by the bismuthene. So far, there is still challenge on the material preparation due to the instability of these 2D materials under atmosphere. The synthesis or growth of materials integrated with the technique of surface protection should be associated with the device fabrication to establish a complete process for particular application. This review provides a complete and methodical guideline for scientists to further research and develop the hazardous gas sensors of these 2D materials in order to achieve the purpose of environmental protection.

本综述首先介绍了石墨烯以外的元素二维 (2D) 材料的本征和电子特性。然后全面回顾了有关使用这些二维材料进行气体传感应用的研究。总体而言，使用其中大部分可以有效检测碳基、氮基和硫基气体。对于有机蒸气的传感，硼烯、磷烯和砷烯可能表现良好。此外，铋可以有效地监测 G 系列神经毒剂。到目前为止，由于这些二维材料在大气下的不稳定性，材料制备仍然存在挑战。与表面保护技术相结合的材料的合成或生长应与器件制造相关联，以便为特定应用建立完整的工艺。这篇综述为科学家们进一步研究和开发这些二维材料的有害气体传感器以达到环境保护的目的提供了一个完整的、有条理的指导方针。
