Hydrogen, a clean-burning energy, is of key importance to various industrial applications, including fuel cells and aerospace and automotive industries. However, hydrogen gas is ordorless, colorless, and highly flammable; thus, appropriate safety protocol implementation and monitoring are essential. In this report, we introduce fabrication of Pt-decorated reduced graphene oxide (Pt_rGO) by using facile chemical reduction for transducer of hydrogen gas sensor. The resulting Pt_rGO-based sensor exhibited a high sensitivity to hydrogen gas at unprecedentedly low concentrations (1 ppm) and long lifetime originated from strong immobilization on the sensor electrode substrate. |
