Synthesis of MnWO4 nanorods and its electrical and electrochemical properties

Abstract

The MnWO4 nanorods were successfully synthesized by surfactant assisted ultrasonics method and characterized its structural (XRD), morphological (SEM) electrical (solid state impedance) and electrochemical (CV) properties. The X-ray diffraction patterns inferred the formation of highly crystalline monoclinic structure of MnWO4. The formation of nanorods with the aspect ratios of 30–40 nm were reveals from SEM image. The maximum d.c. electrical conductivity was found to be 4.40 × 10−5 S/cm at 570°C for MnWO4 nanorods prepared by surfactant assisted ultrasonic method. The quasi-rectangular behavior of cyclic voltammogram inferred the supercapacitive behavior of the prepared MnWO4 nanorods.
