摘要

We report magnetically separable Fe2O3/g-C3N4 nanocomposites as a photocatalyst under visible-light irradiation in this study. The Fe2O3/g-C3N4 nanocomposites were synthesized through a two-step hydrothermal method. The Fe2O3 with cocoon-like shape was obviously dispersed on the surface of g-C3N4 with porous and layered nanostructure as seen from micrographs of the particles. Furthermore, the magnetic conversion of the samples was studied via vibrating sample magnetometer technology. It was found that the saturated magnetization Ms of the Fe2O3/g-C3N4 nanoparticles obviously decreased in the presence of g-C3N4, and the photocatalytic activity of the samples investigated by degrading Rhodamine B suggested that the Fe2O3/g-C3N4 photocatalyst was prior to the pure Fe2O3 and g-C3N4 samples. In addition, the magnetically separable ability of Fe2O3/g-C3N4 nanocomposites was efficiently exhibited by an external magnet.
