Abstract

Binary metal oxides composed of molybdenum-vanadium oxides are promising candidates for supercapacitors. Here, we report the synthesis of one-dimensional V_0.13Mo_0.87O_2.935 nanowires through a facile one-step hydrothermal method. This nanowire presented a high specific capacitance of 394.6 F g^-1 (1 mV s^-1) as an electrode applied to the supercapacitor. Importantly, this electrode showed a perfect rate capability of 91.5% (2 to 10 A g^-1) and a continuous verified outstanding cyclic voltammetry of 97.6% after 10,000 cycles. These superior electrochemical properties make the synthesized V_0.13Mo_0.87O_2.935 nanowires a prospective candidate for high-performance supercapacitors.
