Synthesis of Ag3PO4/Ag/g-C3N4 Composite for Enhanced Photocatalytic Degradation of Methyl Orange

In this study, we have successfully constructed Ag3PO4/Ag/g-C3N4 heterojunctions via the hydrothermal method, which displays a wide photo-absorption range. The higher photocurrent intensity of indicates that separation efficiency photogenerated electron–hole pairs is than both Ag3PO4 and Ag/g-C3N4 pure substances. It confirmed efficient attributed to heterojunction material. Under visible light irradiation, Ag3PO4/Ag/g-C3N4-1.6 can remove MO (~90%) at rate or Ag/g-C3N4. Its degradation 0.04126 min−1, 4.23 6.53 times Ag3PO4, respectively. After five cycles testing, photocatalyst still maintained high photocatalytic activity. excellent photocatalysis under ultraviolet-visible due carriers brought about by construction heterostructure. Additionally, specimens be easily recycled with stability. effects hydroxyl superoxide radicals on process organic compounds were studied using electron paramagnetic resonance spectroscopy radical quenching experiments. Therefore, composite used as an recyclable UV-vis spectrum-driven for purification pollutants.
