Boosting the performance of solar light driven CeO2/BiVO4 anchored g-C3N4 nanocomposites: A systematic study toward the development of a photocatalytic and antibacterial activity

The ever-growing human population the energy and environmental crises are the top-most problems in this society. A grateful method of the photocatalytic process was initiated to remove the organic materials from the waste water to resolving environmental pollution challenges. In the process we creating the innovative photocatalysts with effective light transformation and harvesting capabilities in the waste water treatment process. Herein, the hydrothermal route followed by annealing method was used to synthesize the novel photocatalyst of CeO2/BiVO4/g-C3N4 nanocomposites (CBG NCs). The structural, surface morphological, and optoelectronic properties of the CBG nanocomposites were examined using XRD, FE-SEM, UV-Vis, and PL to confirm the material composition. Furthermore, the prepared CBG nanocomposites were subjected to evaluate the photodegradation performance using with methylene orange (MO) dye under the visible light. As a result, the CBG NCs demonstrates the maximum photodegradation performance of 90% with remarkable stability after five consecutive cycles. Additionally, antimicrobial activities were detail explored with the synthesized catalyst against the gram-positive Staphylococcus aureus (S.aureus) and gram-negative Escherichia coli (E.coli) microorganisms. As demonstrated in results, the CBG NCs (75 g/mL) had a considerable zone of inhibition of 21 ± 1.1 mm in E. coli and 15 ± 1.2 mm in S.aureus. Based on this effective performance of the photocatalytic and antibacterial response of the synthesized CBG nanocomposites were considered as the one of the highly active photocatalyst. The present research offers a possible approach to increase the photocatalytic activity and remove aquatic pollutants for this advanced dye-degradation and antibacterial activity.
