%X To improve the quality of cuprous oxide produced by electrochemical reduction, the source, mechanism and elimination of metal copper in Cu2O is investigated. The metal copper in Cu2O came from the cathode reaction: Cu2O + H2O + 2e = 2Cu0 + 2OH. K2Cr2O7 and diaphragm were used separately to decrease the content of Cu0 in Cu2O product, and significant improvement was resulted.
