Photocatalytic Evaluation of Fe<sub>2</sub>O<sub>3</sub>-TiO<sub>2</sub> Nanocomposites: Influence of TiO<sub>2</sub> Content on Their Structure and Activity.
Ontology highlight
ABSTRACT: In this study, Fe2O3-TiO2 nanocomposites with different TiO2 contents (1-50%) were synthesized via a solvothermal method using pre-formed α-Fe2O3 nanoparticles as cores. We systematically evaluated the influence of TiO2 loading on the nanocomposites' structural, morphological, optical, and photocatalytic properties. X-ray diffraction revealed the coexistence of hematite and anatase phases, with an increase in TiO2 content inducing reduced crystallite size, enhanced dislocation density, and microstrain, indicating interfacial lattice distortion. Scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS) showed a uniform elemental distribution at low TiO2 contents, evolvi
