摘      要：Cu_2O nanocrystals were synthesized by irradiating an aqueous solution of CuSO_4·5H_2O(1.25g),polyvinyl alcohol(PVA,0.8 g),and isopropanol(3.1 mL).The products were characterized by powder XRD,TEM and SEM. Methyl orange degradation under visible light using the Cu_2O nanocrystals as catalyst was studied by UV-Vis absorption *** results show that the products are nanocrystals of pure Cu_*** and size of the nanoparticles are affected by the irradiation dose and pH value of the initial *** Cu_2O nanocrystals of 116 nm in size can be obtained at the initial pH of 8.0 and 280-kGy *** 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_2O particles.
