GO/2D WS2 Based Humidity Sensor†
AbstractIn this work, 2D WS2 nanosheets prepared by the exfoliation of WS2 with Li-intercalation was combined with GO produced by the Hummer method for humidity sensing applications. The GO and WS2 solutions were mixed with an equal concentration and coated on conductometric transducers. Sensing measurements towards humidity (0–80% RH) at room temperature revealed that the humidity response of hybrid was substantially higher by a factor of 3–9 depending on the RH value compared with those of GO and WS2. Moreover, no cross sensitivity to common gaseous compounds was observed. Therefore, the GO/2D WS2 composite is a highly promising humidity sensor.
