Banana peel extract for CeO2 nanoflower synthesis: Enhancing photocatalytic activity for methyl orange dye removal and bactericidal effects

The cube architecture associated with the CeO2 nanoflowers (NFs) that generated, which had an average crystallization width of 7 nm, has been confirmed by X-ray crystallographic investigations. The method used is environmentally acceptable since it converts wasted banana peel extracts into CeO2 nanoflower. On the basis of artwork obtained from a High-Resolution Transmission Electron Microscope (HR-TEM), CeO2 nanoparticles have been observed to possess a spherical shape and an average particle diameter of 21 nm. To take the purpose of this study, green-fabricated CeO2-NFs were used to investigate the photocatalytic oxidation of methyl orange (MO) dye when exposed to sunshine. CeO2 nanofibers showed a degradation performance of 98% when compared to methyl orange dye. Evidently is a possibility that this may be caused by the presence of CeO2 nanoflowers, whereby enhance the interaction of electrons, which are holes dissolution, and adherence. Upon a single day of being exposed, the biocidal potential was tested against both gram-positive and gram-negative bacteria, including E. coli, B. cereus, and S. aureus, among others. Due to the fact that its 32 mm minimum inhibitory concentration (MIC) for B. cereus was the highest among conventional medicines. As shown by the extraordinary capabilities of WBP@CeO2 tiny particles, manipulating of flexible tiny particles to feed the purpose of achieving effective and customizable infections and dermatologist advancements is really stunning.
