Comparative response of the ZIF-67/rGO sensor for NH3 and RH. (a) Response with different concentrations of NH3; (b) response of the sensor against humid conditions [(i) 300 and 750 μL water, which are equivalent to the volume of NH3 solution introduced in the chamber to produce 20 and 50 ppm NH3 vapors, respectively; (ii) 55 and 75% RH inside the sensing chamber]. Inset in (b) shows the enlarged portion of the curve marked with a circle. Note that all the experiments were conducted at RT.
