The increasing global concerns regarding environmental pollution have led to a growing demand for innovative materials that can effectively address these challenges. In response to this pressing need, our study focuses on the development and comprehensive characterization of a novel nanocomposite material composed of barium hexaferrite (BaFe12O19) nanoparticles supported on graphitic carbon nitride (g-C3N4). The primary objective of this research is to introduce a powerful and sustainable solution for the efficient removal of organic pollutants, exemplified by Rhodamine B (RhB), through advanced photocatalytic processes. Synthesis and Characterization: The synthesis of the BaFe12O19/g-C3N4 nanocomposite followed a systematic approach, involving a hydrothermal synthesis method followed by controlled calcination. This meticulous process resulted in the formation of a well-dispersed assembly of BaFe12O19 nanoparticles on the g-C3N4 support. This specific design was aimed at enhancing the photocatalytic activity of the material. To thoroughly understand the properties of the nanocomposite, an array of advanced analytical techniques was employed. X-ray diffraction (XRD) revealed the crystal structure, confirming the successful formation of the composite. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) provided insights into the morphology of the material, showcasing the uniform distribution of nanoparticles on the support. Fourier-transform infrared spectroscopy (FTIR) helped identify chemical bonds and functional groups in the nanocomposite. Collectively, these characterizations substantiated the material s structural integrity and suitability for its intended purpose. Magnetic Properties and Environmental Compatibility: One of the distinctive features of the BaFe12O19/g-C3N4 nanocomposite is its magnetic behavior, evaluated through vibrating sample magnetometry (VSM). The material exhibited superparamagnetic properties, with a notably high saturation magnetization. This inherent magnetic quality enables the nanocomposite to be easily separated and recycled after the photocatalytic process. This recyclability underscores the practicality and environmental friendliness of the material, making it a sustainable solution for environmental remediation. Photodegradation Performance: The core purpose of the BaFe12O19/g-C3N4 nanocomposite is its remarkable ability to photodegrade Rhodamine B (RhB) under visible light irradiation. In our systematic evaluation, the nanocomposite displayed exceptional photocatalytic efficiency, with over 90% degradation of RhB achieved within a short 60-minute timeframe. This impressive performance is attributed to the synergistic interaction between the BaFe12O19 nanoparticles and the g-C3N4 support. This interaction promotes efficient charge separation and utilization, ultimately enhancing the photocatalytic degradation process. Reusability and Sustainability: To assess the nanocomposite s practicality and long-term viability, recycling experiments were conducted over multiple cycles. These experiments unequivocally demonstrated the material s sustained high photocatalytic activity. This finding affirms its stability and underscores its potential as a reliable and reusable remediation tool. The ability to maintain its efficiency over multiple cycles is a critical aspect of its environmental sustainability. Conclusion: In conclusion, our study introduces a magnetic recoverable nanocomposite composed of BaFe12O19 nanoparticles supported on g-C3N4, offering a transformative and sustainable solution for the efficient photodegradation of organic pollutants such as Rhodamine B. The amalgamation of exceptional magnetic properties, superior photocatalytic efficiency, and recyclability positions this nanocomposite as an exemplar of innovative materials designed to address environmental contamination challenges through photocatalysis. This research holds great promise for practical applications in environmental remediation processes and emphasizes the potential of advanced nanomaterials in advancing environmental sustainability. The BaFe12O19/g-C3N4 nanocomposite stands as a versatile platform for future research in the field of advanced photocatalysis and environmental remediation, with the potential to make a significant positive impact on our environment.
