Embodiment 1

[0031] High-purity copper nitrate dihydrate solid particles, hexamethylenetetramine particles, and potassium bromide particles are used as raw materials. First take 0.168g of hexamethylenetetramine (HMT) and 0.362g of copper nitrate dihydrate Cu(NO 3 ) 2 Put it into a clean beaker, add 15mL of deionized water and stir in a magnetic stirrer for 15min, after the stirring is completed, add 0.77g of potassium bromide (KBr) and continue stirring for 10min to fully react the medicine and obtain a mixed solution; pour the mixed solution Put it into a polytetrafluoroethylene lining, put it into a stainless steel high-pressure reaction kettle and seal it. The reaction temperature is 95°C and the reaction is sealed for 2 hours; Pour the precipitate into a clean porcelain cup, dry it at a temperature of 65°C, grind and collect it, and obtain a light green powdery copper hydroxy bromide sample.
