Abstract MoO 3 , with advantages of abundance, non‐toxicity and multiple oxidation states, has recently been attracted increasing attention in supercapacitors field as a potential electrode material. Here, a novel composite TiO 2 /MoO 3 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 F g −1 at the current density of 1 A g −1 , which is higher than pure MoO 3 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 TiO 2 nanoparticles and MoO 3 nanobelts and the increment of specific surface area. This work would not only promote the study about MoO 3 ‐based electrode materials in supercapacitors, but also extended to other transition metal oxides with similar structures.
