Abstract
A method for preparing copper-nickel cobaltate nanowires includes steps of: (1) dissolving a soluble nickel salt, cobalt salt and copper salt in ultrapure water, and preparing same into a mixed salt solution A; (2) adding 1-4 mmol of sodium dodecyl sulfate to solution A, and dissolving same with stirring; (3) dissolving 12-30 mmol of hexamethylenetetramine in 20 mL of ultrapure water to form solution B; (4) slowly dropwise adding solution B to solution A via a separatory funnel to form solution C, and stirring same for 0.5-1 h; and (5) further transferring same into a 100 mL reaction vessel, reacting same at 100-160° C. for 8-20 h, suction filtration and washing, and drying same at 40-60° C. in a vacuum oven, and further reacting same at 350-800° C. for 1-4 h in a muffle furnace.
