Preparation of Composite Particles Containing Nano-CuO and Micron Flake Graphite

Abstract

Nano-CuO particles are prepared by using Cu(NO3)2 and NH4HCO3 as the starting materials and pure water as the solvent. And use high-energy ball milling method to make nano-CuO particles embeded in the crystalloid surface of graphite to form composite particles. The products of nano-CuO and composite particles are characterized by using techniques such as X-ray powder diffraction, FTIR-spectroscopy, scanning electron microscopy, and separator-size analyzer. The results show that the average size of CuO particles is 11.2nm, the Median diameter of composite particles is 8.43μm. After the graphite is rapidly ball milled and loaded nano-CuO particles. The lamellar and pore structure of graphite are well maintained, And nano-CuO particles are loaded on the top of the hole and the hole wall.
