Method for preparing various-shape metal copper nano materials through low heat solid phase chemical reaction

The invention aims at providing a preparing method for metal copper simple substance nano materials. According to the method, cheap solid metal salt and solid ascorbic acid are used for synthesizing the metal Cu nano materials through the low heat solid phase chemical reaction. In the reaction process, the shape and size of products are adjusted by adding sodium fluoride, sodium citrate and hexadecyl trimethyl ammonium bromide. The raw materials adopted in the method are cheap and easy to obtain, the reaction process is simple, energy consumption is low, the yield is high, and environment friendliness is achieved. The metal nano materials prepared in the method are widely applied to the fields of light, electricity, catalysis and the like.
