Abstract

Platinum (Pt) loaded reduced graphene oxide (rGO)/zinc oxide (ZnO) nanocomposite were fabricated by using a combination of sputtering system and pulsed laser ablation in liquid method. The structure and morphology of the rGO/ZnO/Pt hybrid nanocomposites were characterized by field emission X-ray diffraction (XRD), Raman spectroscopy, and scanning electron microscopy (FESEM). The gassensing properties of the fabricated sensors were investigated for hydrogen (H2) at different operating temperatures. The obtained rGO/ZnO/Pt ternary composite exhibits outstanding sensing response towards H2, almost 7.5 times and 3.0 times higher than that of pure ZnO and ZnO/rGO, respectively. These results show that the combination of noble metals nanoparticles with rGO and ZnO can impart new gas sensing functionality that is potentially useful for H2 sensing applications.
