| ABSTRACT |
|
Alumina/ferric oxide (Al2O₃/Fe2O₃) composite nanofibers were fabricated via electrospinning followed by heat treatment. Structural characterization revealed mesoporous morphology with high porosity and surface area and uniform dispersion of catalytically active Fe2O₃ nanoparticles. Catalytic evaluation for ethanol dehydration demonstrated superior performance for nanofibers containing 5 wt% Fe2O₃, attributed to their unique structural features. Further enhancement was achieved by incorporating palladium oxide (PdO), resulting in improved catalytic activity, particularly in ethylene productivity. Surface acid properties were altered with PdO addition, suggesting a role of Lewis acid sites in augmenting catalytic performance. The developed PdO/Al2O₃/Fe2O₃ nanofibers exhibit stable performance over multiple cycles, offering promising prospects for efficient ethanol dehydration catalysts. |
