Shaped-Controlled Synthesis of Nanosized Cuprous Oxides by Hydrothermal Oxidation Method

Abstract

Nanoscaled cuprous oxides were synthesized using the reaction between metallic copper and aqueous hydrogen peroxide solution in isothermal conditions.The resultant solids are characterized by XRD, SEM, TEM, BET techniques.The obtained products are mainly cuprous oxides with different morphologies.The size, shape and aspect ratio of products can be readily controlled by aging time and additive amounts.The present controlled synthesis method yield some kinds of highly crystalline metal oxide nanocrystals.An introduction of HCOOH additive into reaction mixture would significantly affect the controllable size, shape and yield of Cu2O.
