Abstract

Iron oxide (Fe₂O₃) nanoparticles are of great interest compared to their bulk counterpart due to their higher surface area, enhanced possibilities of bio-distribution and high rate of reactivity. In the present work, we report a simple, rapid, and cost-effective method for the synthesis of Fe₂O₃ nanoparticles based on the aqueous-gaseous phase reaction of iron (III) chloride solution by ammonia vapor. Post-physicochemical characterization of these nanoparticles, we have further reported that these positive surface charged containing particles can increase the plant growth under in vitro conditions. Investigations on maize plant show that Fe₂O₃ nanoparticles could have potential as a fertilizer substituent. Moreover, these particles were found to exhibit good photocatalytic activity against Rhodamine B, indicating their potential use toward soil remediation affected with industrial wastewater from dye industries.

摘要

氧化铁 (Fe ₂ O ₃ ) 纳米粒子与其大块对应物相比具有很大的吸引力，因为它们具有更高的表面积、增强的生物分布可能性和高反应率。在目前的工作中，我们报告了一种简单、快速且经济有效的方法，用于合成 Fe ₂ O ₃纳米粒子，该方法基于氨蒸气与氯化铁 (III) 溶液的水气相反应。这些纳米颗粒的物理化学表征后，我们进一步报道了这些含有正表面电荷的颗粒可以在体外条件下增加植物的生长。对玉米植物的研究表明，Fe ₂ O ₃纳米颗粒可能具有作为肥料替代物的潜力。此外，发现这些颗粒对罗丹明 B 表现出良好的光催化活性，表明它们在受染料工业废水影响的土壤修复中的潜在用途。
