Gas sensing characteristics of dense WO₃ NFs, PS (500)-WO₃ NFs, PS (200&500)-WO₃ NFs, and PS (500)-WO₃ NFs funtionalized with 0.1 wt% NOGR flakes in the gas concentration in the range of 1–5 ppm at 350°C toward (a) H₂S and (b) acetone. (c) Limit of detection of the PS (500)-WO₃ NFs funtionalized with 0.1 wt% NOGR flakes toward H₂S down to 100 ppb at 300°C. (d) Selective H₂S detection characteristic of the PS (500)-WO₃ NFs funtionalized with 0.1 wt% NOGR flakes with respect to the interfering analytes at 300°C.
