A nanocomposite consisting of well-dispersed SnO2 and Pt nanoparticles on reduced graphene oxide (see the high-resolution TEM image) exhibited very high responses to hydrogen at concentrations between 0.5 and 3 % in air, with response times of 3–7 s and recovery times of 2–6 s. The sensor was prepared by a straightforward microwave-assisted non-aqueous sol–gel approach.

Abstract
A nanocomposite consisting of well-dispersed SnO2 and Pt nanoparticles on reduced graphene oxide (see the high-resolution TEM image) exhibited very high responses to hydrogen at concentrations between 0.5 and 3 % in air, with response times of 3–7 s and recovery times of 2–6 s. The sensor was prepared by a straightforward microwave-assisted non-aqueous sol–gel approach.File in questo prodotto:
