▎ 摘　　要

We describe a facile in situ hydrothermal fabrication of graphene-MoO3 nanorod bundle composites utilizing sodium salicylate. The structure, morphology and composition of graphen-MoO3 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 MoO3 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 MoO3 nanorod bundles in the hydrothermal process. Due to characteristics of MoO3 and graphene-MoO3 composites, our findings may have implications in the synthesis and fabrication of well-defined functional graphene-MoO3 hybrid materials. It may also provide a general approach for the preparation of graphene-metal oxide hybrid materials. (C) 2011 Elsevier B.V. All rights reserved.
