In this work we report on the development of a simple and fast method for regenerating exhaust graphene based chemi-resistors for NO2 detection. A poisoning effect of the devices due to repeated exposure or to air exposure for > 48 h results in an overall worsening of the sensing response. The presented method consists in the dipping of exhaust devices into ultrapure water at 100 °C for 60 s. The device performances towards analyte are compared with those obtained after the restore by using the developed method. © Springer International Publishing Switzerland 2015.

Abstract
In this work we report on the development of a simple and fast method for regenerating exhaust graphene based chemi-resistors for NO2 detection. A poisoning effect of the devices due to repeated exposure or to air exposure for > 48 h results in an overall worsening of the sensing response. The presented method consists in the dipping of exhaust devices into ultrapure water at 100 °C for 60 s. The device performances towards analyte are compared with those obtained after the restore by using the developed method. © Springer International Publishing Switzerland 2015.File in questo prodotto:
