摘要

Abstract—

Metal molybdate nanocomposites have recently drawn scientific interest for supercapacitor devices, because of their benefits, including good redox reactions and low synthesis costs. This work successfully produced CoMoO4/CuMoO4 nanocomposites (CCMO NCs) grown on nickel foam using a single-pot hydrothermal approach. Furthermore, X-ray diffraction (XRD) confirms that CCMO NCs are well crystalline structure. The formation of the metal – oxygen functional groups of CCMO NCs was confirmed by FTIR spectroscopy. The chemical states of the aimed CCMO NCs were measured using X-ray photoelectron spectroscopy (XPS). Scanning electron microscopy (SEM) and Transmission electron microscopy (TEM) revealed that this material had a rodlike structure. Also, CCMO NCs used as an electrode and employed directly as supercapacitor applications. The CCMO electrode had achieved the specific capacitance (Cs) value of 2500 F g–1 at a current density of 2 A g–1. It also demonstrated cycling stability of 38.46% retention after 10 000 cycles.
