Abstract

In this work, we report on the synthesis of Fe2O3-CeO2 powder-based composites by an original fast solution combustion procedure. Composites with different Fe/Ce molar concentration ratios were synthesized by using different citric acid concentrations and annealing temperatures (500–700 °C) to study the effects on the structural and chemical properties of the final products. Composites showed a majority presence of CeO2 and Fe2O3 crystalline phases, and the slight presence of Fe3O4 which can be completely attenuated by annealing treatments. Our results provide a reliable synthesis method for the fast production of Fe2O3-CeO2 composites with tunable structural and chemical features. © 2025 Elsevier B.V.
