Cuprous oxide (Cu2O) in high yield with controlled shape and size was synthesized\nvia a solution-phase route by reducing cupric sulphate with\nD-glucose. The solution pH shows strong effects on the size and morphology\nof the products. The products were characterized by X-ray power diffraction\n(XRD) and Scanning electron microscope (SEM). The infrared emissivity of\nCu2O was tested by Far infrared emissivity measurer S302. The possible crystal\ngrowth processes have been proposed.
