Abstract

Resistance gas sensors are often fabricated from semiconducting metal oxides (SMOs) and since surface area serve a decisive role in this type of sensors, development of morphologies with high amount of adsorption sites is essential. In this regards, SMOs with 2D nanosheet (NS) morphology are highly promising for gas sensing because of their good crystallinity and large surface area for providing numerous adsorption sites for gas molecules. However, they also have some shortages like relatively high sensing temperature and weak selectivity. In this review, we have discussed various aspects of SMO gas sensors with NS morphology. Pristine, doped, decorated, and composite SMOs with NS morphologies can be successfully used for the detection of toxic gases. Contents of current review may open new concepts for scientists in this field.

纳米片形态金属氧化物气体传感器的研究进展

电阻气体传感器通常由半导体金属氧化物（SMOs）制成，由于表面积在这种类型的传感器中起着决定性的作用，因此具有大量吸附位点的形貌的发展是必不可少的。在这方面，具有二维纳米片（NS）形貌的SMOs由于其良好的结晶度和较大的表面积为气体分子提供了大量的吸附位点，因此在气敏领域具有很大的前景。然而，它们也存在一些不足，如相对较高的传感温度和较弱的选择性。在这篇综述中，我们讨论了具有NS形态的SMO气体传感器的各个方面。具有NS形态的原始、掺杂、修饰和复合SMOs可以成功地用于有毒气体的检测。本文综述的内容可能为该领域的科学家开辟新的思路。
