Fe-Cu Bimetallic Oxide Quantum Dots Coupled with g-C3N4 Nanosheets for Efficient Photo-Fenton Degradation of Phenol

Graphitized carbon nitride (g-C3N4), as a simple and green photocatalytic material, has been widely used in degradation. However, the activity of g-C3N4 was inhibited by poor visible light absorption high photocarrier recombination rate. Metal quantum dots (Qds)/g-C3N4 nanosheets coupled catalysts have attracted more attention Fenton advanced oxidation process due to their charge mobility active sites. In this work, heterogeneous photocatalysts Fe-Cu bimetallic oxide with were prepared. It shows system. Under optimal conditions, removal efficiency 50 ppm phenol reached 99% after 60 min. The catalyst for did not decrease significantly four cycles experiments, had good stability. experimental results show that synergy between semiconductor technology great practical significance.
