Abstract One of the biggest challenges of present-day scientific research is the disposal and/or recycling of environmental waste. In this work, scrap iron obtained from a blacksmith’s backyard was used as precursor for the synthesis of magnetic nanomaterials. Highly magnetic iron based nanomaterials were synthesized in presence of urea and alkali by carefully tuning the precursor concentration and temperature. Characterization of the synthesized nanomaterials was done by powder X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), high-resolution transmission electron microscopy (HRTEM), Fourier-transform infrared spectroscopy (FTIR) and Mossbauer spectroscopy. The magnetic behavior of the synthesized iron-oxide nanoparticles was studied using a squid magnetometer. The net impact of the work reported herein is based on the principle of “Wealth-from-Waste”. Waste scrap iron was converted by a scalable synthetic strategy to useful nanomaterials with potential magnetic applications.

废铁一步法合成高磁性氧化铁纳米材料

摘要 当今科学研究的最大挑战之一是环境废物的处理和/或回收。在这项工作中，从铁匠的后院获得的废铁被用作合成磁性纳米材料的前体。通过仔细调整前体浓度和温度，在尿素和碱的存在下合成了高磁性铁基纳米材料。通过粉末 X 射线衍射 (XRD)、场发射扫描电子显微镜 (FESEM)、高分辨率透射电子显微镜 (HRTEM)、傅里叶变换红外光谱 (FTIR) 和穆斯堡尔光谱对合成的纳米材料进行表征。使用鱿鱼磁力计研究了合成的氧化铁纳米颗粒的磁行为。此处报告的工作的净影响基于“从废物中获得财富”的原则。废铁通过可扩展的合成策略转化为具有潜在磁性应用的有用纳米材料。
