Hydrothermal synthesis and electrochemical performances of 1.7V NiMoO4⋅xH2O||FeMoO4 aqueous hybrid supercapacitor.

Abstract

One-dimensional (1D) NiMoO4⋅xH2O nanorods and β-FeMoO4 microrods are successfully synthesized by simple hydrothermal method without using any organic solvents. X-ray diffraction (XRD) patterns reveal the single phase formation of nickel molybdate (NiMoO4⋅xH2O) and pure monoclinic phase of β-FeMoO4. The growth of one dimensional morphology of both the molybdates are identified from scanning and transmission electron microscopes (SEM and TEM). The cyclic voltammogram envisage the pseudocapacitance behavior of NiMoO4⋅xH2O and β-FeMoO4 through the reversible redox reactions of Ni(3+)/Ni(2+) and Fe(3+)/Fe(2+) ions. An asymmetric supercapacitor is fabricated using NiMoO4⋅xH2O nanorods and β-FeMoO4 as a positive and negative electrode, respectively. The β-FeMoO4||NiMoO4⋅xH2O asymmetric supercapacitor delivers a capacitance of 81Fg(-1) at a current density of 1mAcm(-2). The cell exhibits a high energy density of 29Whkg(-1) and good cycling stability even after 1000 cycles.
