摘　　要：Graphitic carbon nitride(g-C3N4)microspheres supported a-FeO(OH)hybrids[α-FeO(OH)/g-C3N4]were prepared by means of a self-assembly method in deionized water.By UV-visible diffiise reflectance spectroscopy,it has been confirmed thatα-FeO(OH)/g-C3N4 has a wider absorption range thanThe feature ofα-FeO(OH)/g-C3N4 can be attributed to the efficient separation of the electron-hole pairs with photoluminescence spectra.The degradation rate of methyl orange(MO)is up to 99%under the optimal conditions of 110 min,initial concentration of 30 mg/L,anα-FeO(OH)/g-C3N4 dosage of 15 mg as well as visible light.The mechanism for this photocatalytic reaction was proposed,with hydroxyl radicals being a major active catalytic species.
