Preparation method of micro-nano porous copper ball, product prepared through preparation method and application of micro-nano porous copper ball

The invention belongs to the technical field of nano material preparation, and particularly discloses a micro-nano porous copper ball preparation method, a product prepared through the micro-nano porous copper ball preparation method and application, the micro-nano porous copper ball preparation method comprises the following steps that S1, copper salt is dissolved with water to prepare a copper salt solution, and then an inducer is added to be evenly mixed; and S2, the mixed solution obtained in the step S1 is mixed with a reducing agent, a heating reaction is conducted, centrifugation and washing are conducted after the reaction is completed, and the micro-nano porous copper balls are obtained. According to the preparation method, the halide salt inducer is added into the copper salt solution, regulation and control are performed through the inducer, then the reducing agent is added for reaction, the micro-nano porous copper balls are prepared, the particle size of the micro-nano porous copper balls is unif
