High-response dual-purpose NO2 sensor with layered-Bi2WO6 sensing electrode

[Display omitted] •Layered Bi2WO6 increases TPB area and provides more active sites.•Sensor has the prospect of a dual-purpose to detect NO2 in air and automobile exhaust.•Sensor sensitivities are 13.4 and 65.83 mV/decade in 1–4 and 6–50 ppm NO2.•Detection limit as low as 1 ppm. In this work, we suc...
