Facile synthesis of NiWO4/reduced graphene oxide nanocomposite with excellent capacitive performance for supercapacitors

摘要: Abstract NiWO 4 /reduced graphene oxide (NWG) nanocomposite was successfully synthesized through a facile one-pot solvothermal method for the first time. The resulting is composed of nanoparticles that are uniformly attached on sheets by in situ reducing. as-prepared NWG composite has been systematically characterized Powder X-ray diffraction, Fourier transform infrared spectra, Raman spectroscopy, Thermogravimetric analysis, Scanning electron microscopy, Transmission photoelectron and Brunauer–Emmett–Teller analysis. capacitive performances as electrode material investigated. It found exhibits high specific capacitance up to 1031.3 F g −1 at current density 0.5 A g . greatly enhanced performance can be attributed synergetic effect RGO, which provides conducting channels active sites. cyclic stability tests demonstrated no decreases its initial values after 5000 cycles, suggesting such hybrid possesses great potential application energy-storage devices.
