Synthesis of MoO3 nanobelts/reduced graphene oxide by one-step hydrothermal method and the corresponding electrochemical properties
To improve the energy storage performance of MoO3 as the supercapacitor electrode materials,the MoO3 nanoribbon/reduced graphene oxide(RGO)composites were synthesized by one-step hydrothermal method.The phase structure,microstructure,and electrochemical properties of the composites were characterized by X-ray diffraction analysis,scanning electron microscopy,Fourier transform infrared spectroscopy,cyclic voltammetry curves,and constant current charge discharge curves.The results show that,the MoO3 nanoribbon/RGO composites are successfully fabricated by the one-step hydrothermal method.Encouragingly,the specific capacitance of the composite materials is increased by 17.5％,compared with that of pure MoO3 as 228 F·g-1.Furthermore,the MoO3 nanoribbons are wrapped by RGO or attached to the surface of RGO in the composites,enhancing the electrical conductivity and structure stability,and then improving the electrochemical performance.
