Synthesis and Characterization of g-C₃N₄/α-Fe₂O₃ Composites with Enhanced Photocatalytic Activity

Abstract:

A novel composite photocatalyst g-C₃N₄/α-Fe₂O₃ was prepared through calcination method. The photocatalysts were characterized by thermogravimetric analysis (TG), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR). The obtained g-C₃N₄/α-Fe₂O₃ composites show high efficiency for the degradation of Rhodamine B (RHB). The optimum photocatalytic activity of g-C₃N₄/Fe₂O₃ at a g-C₃N₄ content of 8.6% under visible light irradiation is almost 4.8 times as high as that of pure α-Fe₂O₃. The enhancement in visible light photoactivity of g-C₃N₄/α-Fe₂O₃composites was attributed to the introduction of g-C₃N₄ and the interaction between g-C₃N₄ and α-Fe₂O₃.
