Description
Summary:Multifunctional bismuth ferrite (BFO) nanoparticles were successfully synthesized using the co-precipitation technique. pH being a key factor in co-precipitation technique was used to optimize the phase pure synthesis of BFO. The undergone structural changes were examined using XRD. The XRD result shows the distortion in rhombohedral structure of the synthesized sample. Under Ultraviolet-visible spectroscopy, the occurrence of d–d transition and C–T transition taking place in BFO sample was investigated. In addition, the band gap values of BFO1, BFO2 and BFO3 were determined using Tauc’s plot and the values are 2.18 eV, 2.18 eV and 2.12eV, respectively. The suppression of modes of vibration in BFO explains the structural distortion caused by reducing agent; these results are consistent with the XRD results. Finally, through electrochemical analysis the redox behavior and the electron hole transport of the samples were analyzed to identify the suitable sample for photocatalytic performance. EIS spectra were carried out to understand the charge transfer resistance of the samples. The electrostatic interaction of catalyst with Fenton reagent and target material was performed at different ranges of pH 3 to 10 which shows enhanced photocatalytic activity toward picric acid (PA).
