Embodiment 1

[0031] Embodiment 1 prepares the best Cu 2 (OH) 3 The whole process of Cl nanosheets.

[0032] Copper nitrate (Cu(NO 3 ) 2 ), hexamethylenetetramine (HMT) and sodium chloride (NaCl) as raw materials, first take 0.210g hexamethylenetetramine (HMT) and 0.362g copper nitrate (Cu(NO 3 ) 2 ) into a clean beaker, add 15ml of deionized water and stir in a magnetic stirrer for 15min, add 0.438g of sodium chloride (NaCl) and continue stirring for 10min after the stirring is completed, so that the medicine can fully react, and pour the reacted liquid into Heat in a polytetrafluoroethylene reactor with a volume of 25ml and seal at a reaction temperature of 95°C for 2 hours. After the reaction, when the temperature of the reaction kettle drops to room temperature, take out the liquid in the kettle and wash it several times with deionized water, pour the precipitate into a clean porcelain cup, dry it at 65°C, grind and collect it, and then get light green Powdered copper hydroxychlor...

Abstract

The invention discloses a copper hydroxychloride nanosheet and a preparation method thereof, and belongs to the technical field of IB family hydroxychloride nanomaterials. The copper hydroxychloride nanosheet is lamellar and is of a lamellar structure, and the surface of the nanosheet is flat and smooth. The preparation method comprises the following steps: firstly mixing and stirring copper nitrate and hexamethylenetetramine, then adding sodium chloride, and continuously stirring; then carrying out a sealing reaction at the temperature of 95 to 135 DEG C in a reaction still for 2 to 8 h; andfinally carrying out washing, drying and grinding to obtain the light-green powder-like hydroxychloride nanosheet. A sealing high-temperature heating method with the reaction still is adopted firstly,so that the synthesized copper hydroxychloride nanosheet is high in purity, smooth in surface and complete in appearance; and copper hydroxychloride is an extremely important raw material for synthesizing copper oxide and copper chloride, and also can serve as a nutrient element additive of animal feeds and a catalyst of chemical reactions.

Description

technical field [0001] The invention belongs to the technical field of IB group hydroxychloride nanomaterials, and particularly provides a simple, novel and efficient method for preparing copper hydroxychloride nanosheets. Background technique [0002] Due to its unique properties such as small size effect, surface effect, quantum size effect, and macroscopic quantum tunneling effect, nanomaterials have characteristics that ordinary materials do not have in terms of light, electricity, magnetism, and sensitivity. Therefore, nanomaterials have received more and more attention and applications in recent years. For example, it has been widely used in optical materials, electronic materials, magnetic materials, sintering of high-density materials, catalysis, sensing, and ceramic toughening. [0003] In recent years, compound semiconductor materials of copper metal in group IB have been widely used in the fields of electronics, optoelectronics and electrochemistry. Copper hydro...
