Preparation and Antibacterial Performance Study of CeO2/g-C3N4 Nanocomposite Materials
In response to the challenges of food spoilage and water pollution caused by pathogenic microorganisms, CeO<sub>2</sub>/g-C<sub>3</sub>N<sub>4</sub> nanocomposites were synthesized via one-step calcination using thiourea and urea as precursors. Steady-state photoluminescence (PL) spectroscopy analysis demonstrated that 8 wt% CeO<sub>2</sub>/g-C<sub>3</sub>N<sub>4</sub> exhibited superior electron-hole separation efficiency. Quantitative antimicrobial assays demonstrated that the nanocomposites displayed enhanced bactericidal activity against <i>Escherichia coli</i>, <i>Ralstonia solanacearum</i>, and <i>Staphylococcus aureus</i>. Electron paramagnetic resonance (EPR) spectroscopy analysis verified the generation of hydroxyl radicals (·OH) and superoxide radicals (·O<sub>2</sub><sup>-</sup>) during the photo-Fenton process utilizing CeO<sub>2</sub>/g-C<sub>3</sub>N<sub>4</sub> nanocomposites. Additionally, 8 wt% CeO<sub>2</sub>/g-C<sub>3</sub>N<sub>4</sub> nanocomposites demonstrated enhanced photocatalytic degradation of rhodamine B (RhB) and tetracycline hydrochloride (TC) under photo-Fenton conditions.
