| Abstract: | Graphitic carbon nitride(g-C3N4) microspheres supported α-FeO(OH) hybridsα-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 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, 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 major active catalytic species. |
