A facile one-pot method to Au–SnO2-graphene ternary hybrid

In this article, we propose a facile one-pot route for synthesizing Au–SnO2-graphene ternary hybrid. In the system, SnCl2 not only as the precursor of SnO2, but also is employed as reducing agent for the effective reduction of both GO and HAuCl4 to graphene and Au nanoparticles, respectively. The obtained Au–SnO2-graphene hybrid materials are characterized by atomic force microscopy, transmission electron microscopy, X-ray diffraction, Raman spectrum, X-ray photo-electron spectroscopy, and thermal gravimetric analysis. It is found that the content of Au nanoparticles decorated on the surface of graphene can be simply adjusted by changing the amount of HAuCl4 used in the synthesis process.
