Quick preparation method for multi-shell cuprous oxide nano-spheres

Abstract

The invention relates to a quick preparation method for multi-shell cuprous oxide nano-spheres. Cuprous oxide is prepared from copper acetate serving as a raw material, deionized water serving as a solvent and hydrazine hydrate serving as a reducer at normal temperature, and the multi-shell cuprous oxide nano-spheres are quickly prepared through centrifugal separation and vacuum drying. The preparation method is simple and easy to operate, and can realize quick large-scale production, the product has good morphology and is of a multi-shell structure, the granularity is nano-scale, the diameters of the multi-shell nano-spheres are 300-500nm, the product purity is high and reaches 98 percent, and the preparation method is a quite ideal method for quickly preparing the multi-shell cuprous oxide nano-spheres.
