Abstract

This article presents the data on α-FeO nanoparticles synthesized via Pechini method using iron(III) oxide precursor from steel industry. It is important to highlight the added value that is given to an industrial waste. The samples were characterized by thermal analysis (DTA, TG), X-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FTIR). The TG showed three mass changes, whereas DTA resulted in three anomalies. X-ray diffraction pattern of the samples disclosed rhombohedral structure characteristic of the nanocrystalline α-FeO phase. The crystallite size was estimated for each thermal treatment. Fourier transform infrared spectroscopy confirms the phase purity of prepared nanoparticles. A detailed study on the local structure of the samples was carry out in the region of 800 and 400 cm, where the associated bands of Fe-O bonds are presents. The data have not been reported nor discussed for now.

摘要

本文介绍了通过佩琴尼法使用钢铁行业的氧化铁前驱体合成α-FeO纳米颗粒的数据。强调工业废料所具有的附加值很重要。通过热分析（差示热分析、热重分析）、X射线衍射（XRD）和傅里叶变换红外光谱（FTIR）对样品进行了表征。热重分析显示有三次质量变化，而差示热分析产生了三个异常。样品的X射线衍射图谱揭示了纳米晶α-FeO相的菱面体结构特征。对每次热处理的微晶尺寸进行了估算。傅里叶变换红外光谱证实了所制备纳米颗粒的相纯度。在800和400厘米区域对样品的局部结构进行了详细研究，该区域存在Fe-O键的相关谱带。目前这些数据尚未报告和讨论。
