pH Controlled Synthesis of Tetragonal Cu2O Particles

Cuprous oxide (Cu2O) in high yield with controlled shape and size was synthesized via a solution-phase route by reducing cupric sulphate with D-glucose. The solution pH shows strong effects on the size and morphology of the products. The products were characterized by X-ray power diffraction (XRD) and Scanning electron microscope (SEM). The infrared emissivity of Cu2O was tested by Far infrared emissivity measurer S302. The possible crystal growth processes have been proposed.
