Abstract

Ultra-thin Ni(OH)₂nanosheets and reduced graphene oxide (Ni(OH)₂/rGO) composite was successfully synthesized via a facile solvothermal method. Field emission scanning electron microscopy and high-resolution transmission electron microscopy measurements show the porous Ni(OH)₂nanosheets are flatly supported on rGO sheets to form a two-dimensional composite with high specific surface area (210 m² g⁻¹). Serving as the electrode material for supercapacitors, the Ni(OH)₂/rGO composite exhibits high specific capacitance (1886 F g⁻¹at 5 A g⁻¹, 1362 F g⁻¹at 30 A g⁻¹) and excellent cycling stability (∼70% capacity retention after 1000 cycles at 10 A g⁻¹) due to its unique two-dimensional heterostructure and synergistic effect between Ni(OH)₂and rGO, indicating two-dimensional Ni(OH)₂/rGO composite is promising electrode material for the electrochemical energy storage applications.
