There's something in the air …︁ 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.
