A treatment of graphite fluoride C 2 F with hydrazine vapor resulted in development of conductive surface layer. Exposure of the reduced C 2 F sample to gaseous NH 3 (∼5% in ambient air) was shown to lead to rapid increase in layer resistance. Relative change of resistance averaged over three cycles is ∼14%. Only air purging at room temperature is required to recover the sensor. Quantum chemical calculations showed that NH 3 molecules should interact more readily with partially fluorinated graphitic layer than with graphene.Side view of NH 3 molecule on the top of reduced surface of fluorinated graphene.
