Abstract

Metal sulfide-graphene hybrid materials have attracted increased attention as promising supercapacitor electrode materials. Herein, three-dimensional multi-layered graphene (3D GR) is prepared by chemical vapor deposition using nickel nanowires (Ni NWs) as the template and then, indium sulfide nanosheet arrays (In₂S₃ NSAs) were grown on the 3D GR by hydrothermal synthesis to obtain In₂S₃ NSA/3D GR composite. The hybrid is characterized by scanning and transmission electron microscopy, X-ray diffraction, and Raman scattering. The electrode exhibits a high specific capacitance of 530.7 F g⁻¹ at 1 A g⁻¹. Moreover, the electrode possesses an excellent cycle life with 84% capacitance retention after 20,000 cycles at 1 A g⁻¹.
