Abstract

We have developed a flexible and transparent NO2 sensor based on SnO2-functionalized MoS2 and presented its visible light-assisted gas sensing response for the first time. A mechanism of NO2 detection assisted by visible light was proposed and experimentally verified. The fabricated sensor was able to detect NO2 at various concentrations ranging from 9 down to 3 ppm at room temperature and under visible light illumination. We observed sensitive decrease in the current at the exposure to NO2 while the pristine MoS2-based sensor did not show any significant response.
