Influence of Fuel Type on the Auto-Combustion Synthesis of La2CrMnO6/g-C3N4 Nanocomposites: A Comparative Study of Structural, Optical, and Magnetic Properties Authors

Abstract

The influence of fuel type on the auto-combustion synthesis of La₂CrMnO₆/g-C₃N₄ nanocomposites was systematically investigated to evaluate its impact on structural, optical, and magnetic properties. Various fuels, including glycine, urea, and citric acid, were utilized in the synthesis process to compare their effects on phase formation, crystallinity, and particle morphology. X-ray diffraction (XRD) analysis confirmed phase purity and crystallite size variations, while Fourier-transform infrared (FTIR) spectroscopy provided insights into functional group modifications. The optical properties were examined using UV-Vis spectroscopy, revealing variations in bandgap energy influenced by the fuel selection. Furthermore, vibrating sample magnetometry (VSM) was employed to assess magnetic behavior, highlighting the role of fuel-driven microstructural modifications on magnetic interactions. The findings demonstrate that the choice of fuel significantly influences the physicochemical properties of La₂CrMnO₆/g-C₃N₄ nanocomposites, offering valuable insights for tailoring materials with specific functionalities for catalytic, electronic, and spintronic applications.
