Nano Copper Oxide is manufactured by chemical precipitation method. It has increased electrical conductivity, toughness and ductility, increased hardness., attractive in many fields such as energy conversion, optoelectronic devices, and catalyst. CuO nanostructures have other unique magnetic and super-hydrophobic properties.Can be applied to the catalyst, superconducting materials, thermoelectric materials, sensing materials, glass, ceramics and other fields.
