title: Self-assembling Ni(OH)2/α-Fe2O3composites for pseudocapacitors with excellent electrochemical performance.
abstract: Novel two-dimensional (2D) nanostructured Ni(OH)2nanosheet/α-Fe2O3nanoplate composites (NFCs) were successfully synthesized by a simple two-step solvothermal method where the proportion of α-Fe2O3nanoplates was found to be controllable. These composites achieved excellent performance in aqueous electrolyte due to the synergistic effect between Ni(OH)2nanosheets and α-Fe2O3nanoplates, such as high specific capacitance and long-term cycle stability. The obtained NFC8 possessed a maximum mass specific capacitance of 1745.33F g-1at a current density of 2 A g-1, and with 84.28% retention after 3000 cycles galvanostatic charge/discharge at a high current density of 20 A g-1. The above results show that these novel 2D nanostructured Ni(OH)2/α-Fe2O3composites are promising electrode materials for pseudocapacitors.
