The products were characterized by powder XRD, TEM and SEM. Methyl orange degradation under visible light using the Cu 2 O nanocrystals as catalyst was studied by UV-Vis absorption method. The results show that the products are nanocrystals of pure Cu 2 O. Morphology and size of the nanoparticles are affected by the irradiation dose and pH value of the initial solution. Octahedral Cu 2 O nanocrystals of 116 nm in size can be obtained at the initial pH of 8.0 and 280-kGy irradiation. The nanocrystals have excellent catalytic activity for photodegradation of the methyl orange solution bubbled at the air-flow rate of 750 mL·min –1 , due to the large {111} facets of octahedral Cu 2 O particles.
