MoO3, with advantages of abundance, nontoxicity and multiple oxidation states, has recently been attracted increasing attention in supercapacitors field as a potential electrode material. Here, a novel composite TiO2/MoO3 had been synthesized and characterized by X ray diffraction (XRD), Raman spectra, XPS, scanning electron microscope and transmission electron microscope. The electrochemical results showed the composite has enhanced electrochemical properties with the maximum specific capacitance of 141 Fg(-1) at the current density of 1 Ag-1, which is higher than pure MoO3 at the same test condition. The improved electrochemical properties could be attributed to the synergetic effect and the formation of Ti-O-Mo bonds between TiO2 nanoparticles and MoO3 nanobelts and the increment of specific surface area. This work would not only promote the study about MoO3-based electrode materials in supercapacitors, but also extended to other transition metal oxides with similar structures.
