Abstract

The invention discloses a cotton-mass-shaped cobalt phosphate sphere and a preparation method thereof. The cobalt phosphate sphere is composed of cobalt phosphate nanoribbons. The preparation method comprises the steps: mixing hexamethylene tetramine, phosphate, water and alcohol, and carrying out stirring to obtain a uniform solution; then, adding a cobalt salt, and carrying out uniform stirringto obtain a mixed solution; carrying out a hydrothermal reaction on the mixed solution to obtain a precursor; and calcining the precursor to obtain the cobalt phosphate sphere. The preparation methodis low in reaction temperature, simple in preparation process, high in yield and good in repeatability, the assistance of a surfactant and a template is not needed, and the obtained product is specialin shape, not only has the high reaction activity of a nanomaterial, but also avoids the defect of poor dispersibility of the nanomaterial due to agglomeration and has a wide application prospect infields such as lithium ion batteries, supercapacitors, gas sensing and catalysis.

Description

technical field

[0001] The invention relates to a cobalt phosphate ball with a special shape, and relates to a cotton-like cobalt phosphate ball composed of cobalt phosphate nanobelts and a preparation method thereof, belonging to the technical field of inorganic materials. Background technique

[0002] With the depletion of global fossil energy and the increasing environmental pollution, finding new alternative energy has become an urgent problem for all countries. Cobalt phosphate has a wide range of applications in lithium-ion batteries, supercapacitors, catalysis and other fields, and has become a promising phosphate. At present, there are many methods to prepare cobalt phosphate materials with various shapes. For example, CN201410453227.1 discloses a method for preparing cobalt phosphate powder materials. Materials; CN201510819184.9 discloses a preparation method and application of cobalt phosphate ultra-small nanodisks, ultra-thin nanosheets, and ultra-fine nanowires,...
