Title: WAXBERRY-SHAPED NICKEL COBALT OXIDE NANOMATERIAL AND PREPARATION METHOD THEREFOR
Abstract:
A method for preparing a waxberry-shaped nickel cobalt oxide nanomaterial, comprising: dissolving nickel chloride, cobalt chloride, and urea in deionized water at a molar ratio of 1:2:6, stirring to form a pink solution, then transferring the solution to a high pressure reactor for completely reacting, cooling the solution to room temperature, and drying same to obtain a solid-phase precursor; and performing thermal treatment on the solid-phase precursor by a two-step calcination method to obtain the waxberry-shaped nickel cobalt oxide nanomaterial. The material has a nano-microsphere structure. Nanorods are arranged in a tidy array on the surface of microspheres so that the material has a higher specific surface area of 81m2·g-1, and can be used as an electrode material of a supercapacitor.
