Comparative study on NO2 and H2S sensing mechanisms of gas sensors based on WS2 nanosheets

•WS2 nanosheets with edge size about 10 nm were synthesized by the sulfurization of the WO3 nanomesh.•The sensor based on WS2 nanosheets exhibited p-type sensing properties and excellent selectivity to NO2 gas at a low temperature of 160 °C.•The different sensing mechanisms of WS2 nanosheets for NO2...
