Short summary

We present the development of a simple and fast method for restoring exhaust graphene-based chemi-resistors used for NO2 detection. Exposing the devices repeatedly to gases or to air for more than two days, an overall worsening of the sensing signal is observed. Starting from this hypothesis and from the observation that nitrogen dioxide is soluble in water, we performed a recovery method consisting in the dipping of exhaust devices into ultrapure water at 100°C for 60 sec.
