High interest to gas sensors, especially to hydrogen sensors, is explained by the growing interest to hydrogen as a future energy carrier. On the other hand graphene and nanostructured ZnO demonstrated rising optoelectronic properties especially for gas sensing applications. In order to associate their properties, we have synthesized a ZnO/graphene based nanorods. The non resonant Raman spectra of these nanostructures elucidate the interaction between ZnO and graphene reflecting the structural properties of these hybrids. This work presents too the ability of graphene-ZnO based nanorods to Hydrogen sensing which was fast and reproducible.
