Adsorption Behaviors of Small Molecules on Two-Dimensional Penta-NiN2 Layers: Implications for NO and NO2 Gas Sensors

“…Therefore, it is essential to develop effective gas sensors, which can help humans detect and control these toxic gases, improve the environment, and ensure people’s safety. , Over the past decades, gas sensors are usually fabricated with metal oxide semiconductors. , The discovery of graphene in 2004 and the following emergence of other two-dimensional (2D) materials have broken the dominant position of traditional sensors . 2D materials have large surface areas, ultrahigh carrier mobilities, and rich surface active sites. − The usage of these nanosheets can make up for the shortcomings of conventional metal oxide sensors, such as high energy consumption, poor selectivity, and unfriendliness to the environment, and greatly promote the development of gas sensors. − …”

Studying the Adsorption of Gas Molecules and Defects on Modulating the Electronic Transport Characteristics of Monolayer Penta-BN2-Based Devices

“…Especially petrochemical, coal mining and metal-smelting industries are important sources of toxic gas emissions in the atmosphere, such as NO, NO 2 , C 2 H 2 , and C 2 H 4 are common toxic and harmful gases. − Nowadays, countries around the world are paying more and more attention to environmental protection, and governments of various countries have also implemented a package plan for the monitoring of exhaust gas . As a result, gas sensors have become an extremely important tool due to their excellent gas sensitivity performance. − Meanwhile, 2D materials with their fascinating physical and chemical properties are expected to be the candidate materials for the next generation of portable and low-power gas sensors. − …”
