Abstract

The porousCu₂O@g-C₃N₄ compounds were prepared by hydrothermal method in EG as one reducing agent and medium using copper acetate as Cu sources. The prepared specimens were detected by TEM, XPS, XRD, FL and UV/vis DRS. The empirical conclusion indicate that g-C₃N₄ are two-dimensional nanomaterials and Cu₂O was deposited into g-C₃N₄ between two different layers with a bang. The photocatalytic activity of Cu₂O@g-C₃N₄ was characterized depend on degradated organic dye MB driven by light xenon lamp. The empirical conclusion show photocatalytic activity of Cu₂O@g-C₃N₄ was intensified according the structure of p-n heterojunction that interfaced Cu₂O with g-C₃N₄. The rate of MB decomposition increased from 55.23 to 97.07% compare with unitary g-C₃N₄ photocatalyst. Organic dye MB decomposition rate was reduced from 97.07% to 95.69% for several recycling uses, therefore, Cu₂O@g-C₃N₄ shows higher catalytic ability and fixity. The photodegradation mechanism of Cu₂O@g-C₃N₄ was investigated due to the produced active substances in the photocatalytic organic dye MB system.
