Green Synthesis of Hexagonal Hematite (α-Fe₂O₃) Flakes Using Pluronic F127-Gelatin Template for Adsorption and Photodegradation of Ibuprofen.

ABSTRACT: Hematite (α-Fe₂O₃) with uniform hexagonal flake morphology has been successfully synthesized using a combination of gelatin as natural template with F127 via hydrothermal method. The resulting hematite was investigated as adsorbent and photocatalyst for removal of ibuprofen as pharmaceutical waste. Hexagonal flake-like hematite was obtained following calcination at 500 °C with the average size was measured at 1-3 µm. Increasing the calcination temperature to 700 °C transformed the uniform hexagonal structure into cubic shape morphology. Hematite also showed high thermal stability with increasing the calcination temperatures; however, the surface area was reduced from 47 m²/g to 9 m²/g. FTIR analysis further confirmed the formation Fe-O-Fe bonds,
