Nitrogen Dioxide Gas Sensor Based on Ag-Doped Graphene: A ...

High-performance tracking trace amounts of NO2 with gas sensors could be helpful in protecting human health since high levels of NO2 may increase the risk of developing acute exacerbation of chronic obstructive pulmonary disease. Among various gas sensors, Graphene-based sensors have attracted broad attention due to their sensitivity, particularly with the addition of noble metals (, Ag).

Single-layer stanane as potential gas sensor for NO2, SO2 ...

2019-06-01· A detail investigation for understanding the potential of stanane as a novel sensor for detection of environmental toxic/non-toxic gas molecules, viz. NO 2, SO 2, NH 3 and CO 2 is performed under density functional framework. It is found that among all the possible configurations of monolayer stanane, viz. chair, stirrup and boat, the chair form is noticed to be dynamically most stable through ...
