Abstract

Abstract

In order to improve the low specific surface area of g-C₃N₄, three-dimensional (3D) porous g-C₃N₄ was prepared using high temperature thermal polymerization. Fe₂O₃/g-C₃N₄ catalyst was prepared by compositing the g-C₃N₄ with Fe₂O₃ to improve its visible light response. The decolorization rate of the Fe₂O₃/g-C₃N₄ catalyst reached 100% in 30 minutes with a g-C₃N₄ content of 900 mg, Rhodamine B (RhB) concentration of 20 mg·L^–1, and H₂O₂ content of 15 mmol. The Fe₂O₃/g-C₃N₄ catalyst also demonstrated good performance in degrading other organics; the degradation rates of Methyl orange (MO) and Tetracycline (TC) reached 80% and 90%, respectively, in 30 minutes. This photocatalytic mechanism was explored by active group capture experiments, and the results show that h⁺ and ·OH play an important role in the progress of photocatalysis.
