NdFeO3 Anchored on Co-MOF as nano-photocatalyst for Efficient photo-degradation of TC drug from Water

Abstract

The present investigation involved the fabrication and application of NdFeO₃@Co-MOF to remove antibiotic pollutants from wastewater. The fabrication process of NdFeO₃@Co-MOF involves two steps: combustion and solvothermal techniques. Analysis of as-prepared samples using zeta potential, XPS, scanning electron microscopy, mapping, ultraviolet spectroscopy, and X-ray diffraction revealed the proximity of NdFeO₃ and Co-MOF. The prepared materials were evaluated for its ability to degrade tetracycline. The NdFeO₃@Co-MOF photocatalyst has exceptional photocatalytic performance when exposed to visible light. The photocatalytic activity of NdFeO₃@Co-MOF is notably higher when compared to bare NdFeO₃ and Co-MOF. An optimal degradation efficiency of 98.17% was attained by employing the optimised reaction conditions, which included a TC concentration of 25 ppm and a catalyst dosage of 35 mg. In addition to identifying possible photocatalytic mechanisms, the inquiry analysed the dominant active species. In conclusion, the study found that the optimised nanocomposite, composed of NdFeO₃@Co-MOF, demonstrated notable photocatalytic activity against TC. The prepared composite was further evaluated for antioxidant and anti-inflammatory characteristics exhibiting significant activity.
