Surfactant-modulated preparation of NiMoO4 electrode materials and their electrochemical properties
The different morphologies of self-supported NiMoO4/NF materials were prepared by a one-step hydrothermal method,and the effects of surfactants on the morphology and electrochemical properties of NiMoO4/NF were investigated.The structure and morphology of NiMoO4 were characterized by XRD and SEM,which showed that the addition of surfactant did not change the crystal structure of NiMoO4,but only changed the microscopic morphology of the NiMoO4 material.The electrochemical test results showed that a pair of redox peaks appeared in the CV curves of NiMoO4/NF electrode materials with different morphologies.Meanwhile,the SDS-conditioned prepared NiMoO4/NF microflower had the largest current response values of oxidation and reduction peaks,and formed the largest integral area.The GCD curves showed that the SDS-conditioned prepared NiMoO4/NF has the longest discharge time with a specific capacitance of 1742 F/g at 1 A/g.The retention rate of specific capacitance of the NiMoO4/NF microflower electrode material was 86.8％after 3000 cycles,which is promising for the application of supercapacitor electrodes.
