Abstract

AZnOnanoparticles (NPs)/reduced graphene oxide (rGO) composite was fabricated via a simple one-step solvothermal method with graphene oxide (GO) andZn(NO3)2⋅ 6H2Oas the precursors. The morphology, crystal structure and optical properties of the synthesized materials were characterized by field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), atomic force microscopy (AFM), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), Raman spectroscopy and photoluminescence (PL) spectroscopy. The synthesized composite exhibited rGO layers assorted with tinyZnONPs. rGO supposedly acted as a template in the solvothermal process, that may promote the preferential attachment ofZnONPs and prevented the agglomeration ofZnONPs in the synthesized composite. It was also found that the electrical properties of the composite improved markedly with bareZnONPs, without significantly changing the morphology and crystal structure of theZnONPs. The main aim of this research is to develop an efficient sensor and to understand the effect of graphene in sensing characteristics. The synthesized composite was exposed toH2,COandC2H2gases to confirm its feasibility for gas sensing, and the results showed preferential detection of reducing gases at low temperature.
