A novel electrode material of the three-dimensional (3D) multicomponent oxide of Nickel Cobaltite and Nickel Molybdate heterostructures (NiCo2O4@NiMoO4) has been synthesized by a facile microwave irradiation method, and an X-ray diffractogram (XRD) measurement confirms the materials' crystalline phase. A surface composition analysis using XPS was conducted. NiCo2O4, NiMoO4 and NiCo2O4@NiMoO4 has a structure resembling a nanoplate, nanosheet, and coreshell, as demonstrated by HR-SEM and TEM investigation. For NiCo2O4, electrochemical tests revealed pseudocapacitive behavior. Among all NiCo2O4@NiMoO4 displayed excellent supercapacitor performance with a high specific capacitance of 2724 F g−1 at 1 Ag−1 and high energy density of 83.5 Wh kg−1 with catalytic stability.
