Synthesis of Cu 2O crystals by galvanic deposition technique

Abstract

A simple galvanic deposition technique has been developed to demonstrate the deposition of cuprous oxide (Cu 2O) on transparent conducting oxide substrate for the first time. The result shows that the morphologies of galvanically obtained Cu 2O crystals are mainly dependent on the nature of anions in aqueous solution. The presence of NO 3 − ions tends to increase the stability of (111) planes of Cu 2O cubes and makes the crystals develop a fraction of (111) planes at the corners of the Cu 2O cubes, thus resulting in the formation of truncated octahedral Cu 2O crystals.
