摘要

Graphitic carbon nitride(g-C3N4) microspheres supported α-FeO(OH) hybrids[α-FeO(OH)/g-C3N4] were prepared by means of a self-assembly method in deionized water.By UV-visible diffuse reflectance spectroscopy,it has been confirmed that α-FeO(OH)/g-C3N4 has a wider absorption range than g-C3N4.The feature of α-FeO(OH)/g-C3N4 can be attributed to the efficient separation of the electron-hole pairs with photoluminescenee 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,an α-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 maj or active catalytic species.
