Abstract

Reduced graphene oxide (RGO) was synthesized under H2/Ar treatment from 100 °C to 900 °C. RGO-300 shows excellent sensitivity to H2 and a dual sensing mode was observed. The balance between the chemical adsorption capacity and electronic conductivity, and the dominance of either electrons or holes are the key factors.
