Hetrostructured SrFe₁₂O₁₉@g-C₃N₄ nanocomposites applied to linezolid antibiotic degradation under visible induced catalytic process

In this study, a novel visible-light photocatalyst composite named strontium hexaferrite coupled with graphitic carbon nitride (SrFe₁₂O₁₉@g-C₃N₄) was fabricated. The Fourier transform infrared spectroscopy (FTIR) confirmed the presence of metal oxygen vibration in the samples. The X-Ray diffraction spectroscopy (PXRD) claimed the successful synthesis of the samples. The scanning electron microscopy (SEM) techniques signified stacked sheet like morphology of the synthesized photocatalysts. These photocatalysts were further elaborated to check the photodegradation efficiency of catalyst via degrading linezolid antibiotic. The outcomes showed that Degradation efficiency increased substantially up to 87.7% at photocatalyst dose of 1.25 g/L and pH of 5. The scavenger experiments demonstrated that the main components in the photocatalytic degradation of linezolid are hole (h⁺) and superoxide \(\left({{\rm{\bullet }}{\rm{O}}}_{2}^{-}\right)\) $\left({\mathrm{•}\mathrm{O}}_2^{-}\right)$ . It can be concluded that linezolid removal using the SrFe₁₂O₁₉@g-C₃N₄ photocatalytic approach is shown to have an appropriate efficiency based on the findings of this study.
