| Abstract |
A facile one-step method of synthesizing monolayered cobalt-nickel hydroxide nano-crystals ((Co, Ni)(OH)2) is presented using ammonia transfer method in the closed vessel without exfoliation process. The electrode materials are fabricated by deposition of (Co, Ni)(OH)2 on Ni metal substrate for 1 minute by electrophoretic deposition. Thin layer of (Co, Ni)(OH)2 are deposited in average of 50 mg, showing brownish green color. The scanning electron microscope, transmission electron microscope and X-ray diffraction were used to analyze the morphology and crystal structure of (Co, Ni)(OH)2 electrode. The electrochemical performance of (Co, Ni)(OH)2 electrode with various molar ratio of cobalt and nickel as negative electrodes were characterized by cyclic voltammetry in KOH aqueous solution at room temperature. |
