The electrochemical properties and structures of the α-MoO3 materials and the new α-MoO3/CuO composite materials were investigated.The results showed that the electrochemical performance of the new α-MoO3/CuO composite material was better than that of the α-MoO3 material,the specific capacitances of α-MoO3/CuO and α-MoO3 were 3.41 F·g-1and 1.58 F·g-1,and the specific capacitance of α-MoO3/CuO was 2.16 times that of α-MoO3/CuO under the condition of a sweeping speed of 10 mV·s-1;α-MoO3/CuO possessed a good ionic response in the high frequency range and a good electrical conductivity;α-MoO3/CuO had a capacitance of 125.48,55.50 and 28.32 F·g-1 at the current densities of 1,2 and 3 A·g-1,respectively,while the capacitance of α-MoO3 were 55.64,22.31 and 10.75 F·g-1.The results of SEM showed that the CuO particles were distributed more evenly on the α-MoO3;the results of XRD showed that α-MoO3 and CuO existed in the composite structure.
