A new preparation method of Cu from CuO under hydrothermal conditions was investigated. Glucose was employed as reducing agent. Results showed that CuO can be reduced easily to Cu°with glucose as reductant at 220-250°C with NaOH. The reaction conditions such as reaction time, reaction temperature, sodium hydroxide concentration and water filling played key roles in the purity of the products. The proposed method provides an efficient and green conversion of CuO into Cu°without an expensive and toxic reducing agent at low temperatures.
