Abstract:

Imperative necessity for new therapy and catalysts has risen significantly due to infectious agents that are multi-resistant and organic toxins draining into our ecosystem. To address these problems, highly biocompatible Cordia myxa incubated I-ZnO, I-Co3O4, and I-Fe2O3 NPs were prepared and characterized by using a variety of techniques, including ultraviolet–visible spectroscopy (UV–vis), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR). The XRD diffraction pattern confirmed that I-ZnO hexagonal, while I- Co3O4 and I-Fe2O3 cubic structure. UV–vis spectra show the energy bandgap for I-ZnO, I-Fe2O3, and I-Co3O4 3.35 eV, 2.32 eV, and 2.44 eV, respectively. TEM analyses show the patterns of the morphology of I-ZnO as flower-shaped, I-Fe2O3 as rectangular, I-Co3O4 looks like prism crystals. EDX mapping confirmed the elemental presence of Zn, Fe, Co in the samples. The antibacterial study show that the I-NPs have bigger zone of inhibition (ZOI) than pristine NPs. The highest percentage for E-coli strain obtained in this trend (I- Fe2O3)81%>(I-ZnO)76%>(I-Co3O4)63%. Photocatalytic activity results revealed that the MB dye degraded after 80 min and efficiencies of I-(Fe2O3)98.38 %>I-ZnO98.12%>(I-Co3O4)93.93%. Furthermore, the green synthesis strategy certifies a new pathway for minimizing infections, oxidative stress, and degradation of key pollutants from the environment.
