摘要

在这项工作中，我们报道了用原始的快速溶液燃烧方法合成Fe2O3-CeO2粉末基复合材料。采用不同的柠檬酸浓度和退火温度（500 ~ 700℃）合成了不同Fe/Ce摩尔浓度比的复合材料，研究了对最终产物结构和化学性能的影响。复合材料中主要存在CeO2和Fe2O3晶相，少量存在Fe3O4， Fe3O4可以通过退火处理完全衰减。我们的研究结果为快速制备具有可调结构和化学特性的Fe2O3-CeO2复合材料提供了可靠的合成方法。

Synthesis of Fe2O3-CeO2 composites by fast combustion method: A study on citric acid, precursors concentration ratio and annealing temperature effects

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.

期刊介绍： Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage. Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
