Abstract
We describe a facile in situ hydrothermal fabrication of graphene–MoO 3 nanorod bundle composites utilizing sodium salicylate. The structure, morphology and composition of graphen–MoO 3 composites were investigated by means of field-emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), Raman spectroscopy and thermogravimetric-differential scanning calorimetry (TG-DSC). FESEM and TEM studies show that the presence of ordered MoO 3 nanorod bundles in composites, the characterization results of XRD, Raman spectra and TG-DSC analysis confirm the reduction of graphite oxide (GO) to graphene accompanying by the formation of MoO 3 nanorod bundles in the hydrothermal process. Due to characteristics of MoO 3 and graphene–MoO 3 composites, our findings may have implications in the synthesis and fabrication of well-defined functional graphene–MoO 3 hybrid materials. It may also provide a general approach for the preparation of graphene–metal oxide hybrid materials.
