二维材料由于具有大的比表面积和强的表面活性，在气敏领域显示出巨大的应用潜力。除了通常报道的化学发光型气体传感器之外，场效应晶体管（FET）型气体传感器由于其小型化尺寸、低功耗以及与CMOS技术的良好兼容性而引起了越来越多的关注。在这篇综述中，我们的目标是讨论化学电阻和FET型气体传感器的最新发展的基础上的二维材料，包括石墨烯，过渡金属二硫属化物，MXenes，黑磷烯，和其他层状材料。首先给出了这两种传感器的器件结构和相应的制作工艺，并讨论了它们的优缺点。其次，详细分析了本征和非本征因素对二维材料基化学电阻型和FET型气敏元件敏感性能的影响。随后，目前的气体传感应用的二维材料为基础的化学电阻和FET型气体传感器系统。最后指出了二维材料在化学电阻型和场效应管型气敏应用中的前景以及目前存在的问题，为开发具有更好传感性能的二维材料基气敏传感器提供参考。
Two-dimensional (2D) materials have shown great potential for gas sensing applications due to their large specific surface areas and strong surface activities. In addition to the commonly reported chemiresistive-type gas sensors, field-effect transistor (FET)-type gas sensors have attracted increased attention due to their miniaturized size, low power consumption, and good compatibility with CMOS technology. In this review, we aim to discuss the recent developments in chemiresistive- and FET-type gas sensors based on 2D materials, including graphene, transition metal dichalcogenides, MXenes, black phosphorene, and other layered materials. Firstly, the device structure and the corresponding fabrication process of the two types of sensors are given, and then the advantages and disadvantages are also discussed. Secondly, the effects of intrinsic and extrinsic factors on the sensing performance of 2D material-based chemiresistive and FET-type gas sensors are also detailed. Subsequently, the current gas-sensing applications of 2D material-based chemiresistive- and FET-type gas sensors are systematically presented. Finally, the future prospects of 2D materials in chemiresistive- and FET-type gas sensing applications as well as the current existing problems are pointed out, which could be helpful for the development of 2D material-based gas sensors with better sensing performance to meet the requirements for practical application.
