Abstract: Cuprous oxide is used as an antimicrobial and fungicide of fruit trees and is widely used as a catalyst for photodegradation of organic contaminants in the visible light region. Cuprous cuprous oxide was successfully prepared by simple mechanochemical method at any place by varying the amount of reactants added in the system consisting of copper sulphate, sodium hydroxide and glucose without any heat source or complex device, the mode of addition of reactants, the grinding time and the aging conditions of the product. First, CuSO4∙5H2O and NaOH were ground to a size of about 100 μm, respectively. Then, the ground copper sulfate was homogeneously mixed with glucose powder, a reducing agent and dodecyl sodium sulfate (SDS), a dispersing stabilizer. It was then mixed with a suitable amount of the ground NaOH and underwent a simple mechanochemical method of ball milling with an agate mortar to prepare ultrafine cuprous oxide in solid phase consisting of copper sulfate, sodium hydroxide and glucose. The results show that ultrafine cuprous oxide was obtained after 30 min of ball-milling without combustion of glucose as reducing agent when adding NaOH twice. The as-prepared ultrafine cuprous oxide was characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM) and it correspond to a cubic structure with size of 30-40 nm.
