Hydrothermal synthesis of cuprous oxide microstructures assembled from needles

Cuprous oxide (Cu2O) has been successfully synthesized by a hydrothermal method at 200 °C for 2 h using Cu(CH3COO)2·H2O, glycine (C2H5NO2) and NaOH. The morphology of Cu2O is significantly influenced by the concentration of glycine or NaOH.
