Photocatalytic Degradation of Cefixime Trihydrate by Bismuth Ferrite Nanoparticles

Abstract

The present work was carried out to synthesize bismuth ferrite (BFO) nanoparticles by combustion synthesis, and to evaluate the photocatalytic activity of synthesized bismuth ferrite nanoparticles against cefixime trihydrate. BFO nanoparticles were successfully synthesized using bismuth (III) nitrate and iron (III) nitrate by a combustion synthesis method employing different types of fuels such as maltose, succinic acid, cinnamic acid, and lactose. The effects of the different types of fuels on the morphology and size of the bismuth ferrite nanoparticles were investigated. Characterization of the as-obtained bismuth ferrite nanoparticles was carried out by different techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), Energy-Dispersive Spectroscopy (EDS), N2-sorption analysis, Fourier-transform infrared spectroscopy (FT-IR), and ultraviolet-visible (UV–vis) spectroscopy. Photoluminescence studies were also carried out for the various bismuth ferrite nanoparticles obtained. Degradation of cefixime trihydrate was investigated under sunlight to evaluate the photocatalytic properties of the bismuth ferrite nanoparticles, and it was found that the bismuth ferrite nanoparticles followed first-order degradation kinetics in solar irradiation in the degradation of antibiotic, cefixime trihydrate.

Impact of Cr Doping on the Structural, Optical, and Magnetic Properties of Sol–Gel-Synthesized Bi0.80Ba0.10Pr0.10FeO3 Nanopowders

“…This feature is attributed to the confluence of Fe–O and Bi–O stretching and bending vibrations within the BO 6 octahedra of the perovskite structure . Additionally, a small hump near 700 cm –1 is linked to the Bi–O stretching and bending vibration. − The hump at approximately 865 cm –1 is indicative of the entrapped NO 3 ions. The presence of a metal-oxide band within the 400–700 cm –1 interval corroborates the formation of the perovskite structure, a finding supported by other BFO-based material studies. − Furthermore, Ke et al have identified the absorption bands in the 400–600 cm –1 spectral region as fundamental peaks for metal oxides, confirming the successful synthesis of BFO perovskite materials. − …”

Band-gap engineering of zirconia by nitrogen doping in reactive HiPIMS: a step forward in developing innovative technologies for photocatalysts synthesis

“…To quantitatively analyse the degradation kinetics, the MB degradation-rate constant (k) was determined by fitting the kinetic data obtained from the linear fitting curves of -ln(C/C0) versus irradiation time (Figure 9B). The excellent linearity of the plots indicates that the photodegradation rate of MB follows a pseudo-first-order kinetic reaction: -ln(C/C0) = kt, where k represents the photodegradation-rate constant (Nazir et al, 2021). Furthermore, the calculated MB degradation efficiency and degradation-rate constant (k) were plotted against the energy bandgap of the ZrO 2-x N x samples in Figure 10.…”

“…In the IR spectrum of BiFeO 3 , two significant bands were identified. One prominent peak appeared at 560 cm −1 , attributed to Fe-O stretching, while another was observed at 440 cm −1 , related to O-Fe-O vibrations of FeO 6 groups within the perovskite compounds [29].…”
