Structural, optical, and magnetic properties of Co–Dy doped BaFe₁₂O₁₉/g-C₃N₄ nanocomposites: a multifunctional material study

In this research paper, a new form of Ba 0.98 Co 0.02 Dy 0.02 Fe 11.98 O 19 /g-C 3 N 4 nanocomposite was effectively fabricated via combining polymeric g-C 3 N 4 with cobalt and dysprosium doped BaFe 12 O 19 . A hexagonal phase with a crystallite size of 42.55 nm was revealed by the structural investigation of the synthesised materials using XRD. Additionally, it was found that the composite band gap was calculated to be 2.7 eV. FTIR spectroscopy verified the presence of vibrational modes, as well as chemical structure and bonding in the materials. According to FESEM, the hexagonal grain boundary in the prepared nanocomposite is most likely dispersed throughout the surface of g-C 3 N 4 nanosheets. The XPS examination verified that the elements and chemical states of the composite exist in the form of N1s, Co2p, Ba3d, Fe2p, Dy3d, O1s, and C1s. The produced composite specific surface area was determined to be 5.324 m 2 /g. This study provides detailed insights about the structural, morphological, and compositional traits of the nanocomposite for their utilization in many applications such as photo-electrocatalysis, solar cells, lithium batteries, fuel cell supercapacitor, electrocatalysis, and purification and separation.
