Bio-utilization Synthesis of Fe Doped Bismuth Zirconate Mediated by Menthaspicata L. for Photocatalytic, Antibacterial and Electrochemical Applications
摘要
Synthesis and systematic characterization of BZOP: Fe (0–9 mol%) nanomaterials (NMs) was done; it is also applied in photocatalytic activity, antibacterial activity and electrochemical sensing. The composition was found to be monoclinic microstructure as shown by X-ray diffraction (XRD) with a size of crystallites lying between 30.4 and 45.8 nm depending on the concentration of Fe doping. SEM and TEM measurements demonstrated a homogeneous morphology, whereas the existence of the elements including Bi, Zr, Fe, and O was approved by EDS and XPS measurements. An examination of functional groups was done on FTIR, and optical band gap was found to reduce with further addition of Fe with a range of 2.33 to 2.09 eV using UV–Vis spectroscopy. Of all the compositions, BZOP: Fe (5 mol%) showed photo catalytic degradation efficiency of 96% and 98% in case of Methylene blue (MB) and Rhodamine B (RB) dye, respectively. There were better results in antibacterial culture, whether in Gram-negative bacteria or Gram-positive bacteria. Electrochemical analysis through cyclic voltammetry suggested pseudocapacitance with an increased specific capacitance in case of 5 mol% of Fe doping. The NMs were also showed elevated sensitivity in the detection of dextrose and Pb2+ ions even in low concentration as 5 mM. These findings emphasize the potential role of nanotechnology in resolving some of the major issues in the environment by identifying BZOP: Fe (5 mol%) as a multifunctional material in environmental remediation and bio sensing.
