The sensing properties of SnO 2 -graphene composites prepared by a one- pot non-aqueous procedure assisted by microwave treatment have been investigated. The combined characteristics of the microwave heating and the “benzyl alcohol route” allowed to selectively grow, at the temperature of 185 °C and in only few minutes, metal oxide nanoparticles on the surface of reduced graphene (RGO). Chemoresistive devices consisting of a thick SnO 2 /RGO layer on alumina substrates with Pt interdigitated electrodes were fabricated and their electrical and sensing characteristics were investigated.

Abstract
The sensing properties of SnO 2 -graphene composites prepared by a one- pot non-aqueous procedure assisted by microwave treatment have been investigated. The combined characteristics of the microwave heating and the “benzyl alcohol route” allowed to selectively grow, at the temperature of 185 °C and in only few minutes, metal oxide nanoparticles on the surface of reduced graphene (RGO). Chemoresistive devices consisting of a thick SnO 2 /RGO layer on alumina substrates with Pt interdigitated electrodes were fabricated and their electrical and sensing characteristics were investigated.File in questo prodotto:
