Hyaluronic Acid-Mediated Ge0.5Fe2.5O4 Nanoparticles: In Relation to Photocatalytic Performance for Organic Dye Degradation
The present study reports the systematic synthesis, characterization, and photocatalytic evaluation of germanium-substituted iron oxide (Ge0.5Fe2.5O4) nanoparticles with varying concentrations of hyaluronic acid (HA). The synthesized nanoparticles were characterized using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and Brunauer–Emmett–Teller (BET) analysis. The XRD confirmed the formation of Ge0.5Fe2.5O4 with a crystallite size of 19 nm. The FTIR and SEM analysis verified the successful incorporation of Ge and HA into the iron oxide lattice. BET analysis revealed increased porosity upon HA addition, indicating potential benefits for catalytic applications. The photocatalytic efficiency of the nanoparticles was assessed using methylene blue dye degradation as a model reaction. Surprisingly, pristine Ge0.5Fe2.5O4 exhibited an impressive 89.11% degradation rate, greater than (6% and 12%) HA-modified Ge0.5Fe2.5O4 photocatalysts. These findings highlight the complex interaction between surface chemistry, porosity, and catalytic activity.
