Abstract

The challenges associated with efficient removal of ciprofloxacin (CIP), such as low efficiency, high energy consumption, and the generation of harmful by-products have prompted the development of environmentally friendly degradation techniques. This study investigates the synthesis and characterization of nickel ferrite doped with cellulose acetate (NiFe₂O₄/CA) composite films and coupling with Dielectric Barrier Discharge (DBD) reactor to facilitate ciprofloxacin degradation. Scanning electron microscopy (SEM) analysis revealed the presence of spherical NiFe₂O₄ nanoparticles exhibiting enhanced surface particulate morphology and pore structure following the calcination process. This structural modification resulted in improved adsorption capabilities. The SEM images of NiFe₂O₄/CA composite films exhibited consistent catalyst performance in a DBD plasma setup across multiple cycles. Transmission electron microscopy (TEM) illustrated well-dispersed surfaces with a hollow structure and symmetrical distribution of carbon dots (CDs). Energy dispersive spectroscopy (EDS) analysis confirmed uniform dispersion of atomic components in the nanoparticles. X-ray diffraction (XRD) patterns indicated high crystallinity and effective integration of NiFe2O4 and CA, supporting their stability for reuse. X-ray photoelectron spectroscopy (XPS) analysis revealed elemental composition and oxidation status, confirming the successful incorporation of carbon dots and metal-oxygen bonds. Fourier transform infrared spectroscopy (FT-IR) validated the synthesis of NiFe₂O₄/CA composite films, while Raman spectroscopy further confirmed characteristic peaks, affirming efficient fabrication. The degradation results revealed an upsurge efficiency of 86.13 % for 10 mg/L CIP after 60 min of treatment with 9 % NiFe₂O₄/CA films, which outperformed other catalysts reported in previous studies. These findings underscore the distinctive performance of incorporating CA into NiFe₂O₄ NCs and shed light on their potential application for efficient degradation of CIP in the environment.

期刊介绍： Ceramics International covers the science of advanced ceramic materials. The journal encourages contributions that demonstrate how an understanding of the basic chemical and physical phenomena may direct materials design and stimulate ideas for new or improved processing techniques, in order to obtain materials with desired structural features and properties. Ceramics International covers oxide and non-oxide ceramics, functional glasses, glass ceramics, amorphous inorganic non-metallic materials (and their combinations with metal and organic materials), in the form of particulates, dense or porous bodies, thin/thick films and laminated, graded and composite structures. Process related topics such as ceramic-ceramic joints or joining ceramics with dissimilar materials, as well as surface finishing and conditioning are also covered. Besides traditional processing techniques, manufacturing routes of interest include innovative procedures benefiting from externally applied stresses, electromagnetic fields and energetic beams, as well as top-down and self-assembly nanotechnology approaches. In addition, the journal welcomes submissions on bio-inspired and bio-enabled materials designs, experimentally validated multi scale modelling and simulation for materials design, and the use of the most advanced chemical and physical characterization techniques of structure, properties and behaviour. Technologically relevant low-dimensional systems are a particular focus of Ceramics International. These include 0, 1 and 2-D nanomaterials (also covering CNTs, graphene and related materials, and diamond-like carbons), their nanocomposites, as well as nano-hybrids and hierarchical multifunctional nanostructures that might integrate molecular, biological and electronic components.
