摘要：The copper nano-crystalline particles were prepared facilely by a solid solid reaction process of copper chloride dihydrate and potassium borohydride powders at room temperature. The results of various characterizations, such as the chemical analysis, infrared spectrum, inductively coupled plasma-atomic emission spectroscopy (ICP), powder X-ray diffraction and transmission electron microscope, indicated that the resultant was mainly composed of the metal copper nanoparticles with diameter of 30-40 nm, and also contained 14.3% of cuprous oxide crystallites. The phase analysis indicated that the resultant was composed of the metal copper crystal with cubic system and the cuprous oxide with cubic system. The mechanism of room temperature solid solid reaction was discussed briefly.
