a) Electrical responses of pristine MoS2 nanosheets and MoS2–Pd composite to 50 000 ppm H2. b) I–V characteristics of MoS2–Pd composite before and after H2 exposure. c) Electrical response of MoS2–Pd composite exposed to different concentrations of H2 (500–50 000 ppm) by 40 s pulses. d) Recovery time and sensor response of MoS2–Pd composite as a function of H2 concentration. e) Recovery time and sensor response of MoS2–Pd composite as a function of annealing time. f) Cross‐sensitivity of MoS2–Pd composite to 50 000 ppm hydrogen, 50 ppm ammonia, 50 000 ppm acetone and ethanol.
