A kind of nano-flaky copper sulfide material, preparation method and application

Abstract

The invention discloses a nano-flaky copper sulfide material, a preparation method and an application thereof. The key points of the technical scheme are: continuously inject moist sulfur dioxide and carbon monoxide into a water-bath reaction kettle containing an aqueous solution of sodium hydroxide, and electrolyze it under a high-temperature vacuum environment. Reduction reaction to obtain a mixed solution of sodium sulfide, hydrogen sulfide and sulfur element; after cooling the water bath reactor to normal temperature, stir the aqueous solution in the water bath reactor, and discharge the gas in the water bath reactor to obtain a mixed solution of sodium sulfide and sulfur element solution; add copper powder and copper salt into a water bath reactor, react in a high-temperature environment, and obtain nano-copper sulfide coarse material after centrifugation, washing, and drying; the nano-copper sulfide coarse material is passed through multiple groups of side-by-side in the grinding device After the steel ball is subjected to disorderly grinding, a prismatic sheet-shaped nano-copper sulfide material is obtained. Its shape is prismatic sheet-like copper sulfide, the thickness of the middle part is greater than that of the edge, the surface is smooth, the structure is stable, the difference between individuals is small, and it can be mass-produced.
