g-C₃N₄/Fe₃O₄ composites synthesized via solid-state reaction and photocatalytic activity evaluation of methyl blue degradation under visible light irradiation

This study applied the solid-state reaction technique to synthesize g-C₃N₄, Fe₃O₄, and g-C₃N₄/Fe₃O₄ composites in various ratios. XRD confirmed the formation of g-C₃N₄, Fe₃O₄, and a g-C₃N₄/Fe₃O₄ heterostructure. SEM confirmed the rod-shaped structure of Fe₂O₃ and the layered-like fabrication of g-C₃N₄. The E_g of g-C₃N₄/Fe₃O₄ was approximately 1.9 eV, making it a beneficial composite material for visible response in photocatalysis activity, which was confirmed by UV-Vis spectroscopy. Dielectrics were used to study ferrite nanoparticles and provide information on the mechanism of conductivity in the parts of the dielectric that responded to an applied alternating electric field. In polycrystalline ceramics, the resistive and capacitive grains, contributions, electrode specimen interfaces, and grain boundaries may all be distinguished using impedance analysis, a crucial tool for the study of complicated electrical performance. The g-C₃N₄/Fe₃O₄ composite material showed high photocatalytic activity against methylene blue (MB) dye.
