Integration of Fenton and photocatalytic processes in one reaction system may increase the degradation efficiency in wastewater treatments. In this work α- Fe2O3/g-C3N4 composites with different mass percentages of α-Fe2O3 have been prepared in order to catalyze the Fenton and photocatalytic reactions simultaneously. The catalytic efficiency is greatly boosted in the presence of H2O2 under visible-light irradiation compared with single Fenton or photocatalytic reactions. The composite with 0.38% α-Fe2O3 shows the best catalytic efficiency with a reaction rate constant of 0.10 min−1 in the degradation of rhodamine B, which is about 8.4 and 3.7 times higher than that of pure α-Fe2O3 and pure g-C3N4 under the same conditions, respectively. This enhancement of the composites should be ascribed to a synergetic effect between α-Fe2O3 and g-C3N4. Moreover, a reasonable catalytic mechanism for the α-Fe2O3/g-C3N4 composite has been proposed.
