Abstract

In this paper, we decomposed the FeSO₄ at the presence of benzoic acid with weight ratio 1 : 1 at two different temperatures 500 and 600°C. The as-synthesized products were characterized by Fourier Transform Infrared (FT-IR) spectroscopy, powder X-ray diffraction (XRD) and transmission electron microscopy (TEM). FT-IR and XRD results confirmed that the as-prepared product at 500°C is a mixture of intermediate compounds, while the as-prepared product at 600°C is obviously pure with high degree of crystallinity of hematite (α-Fe₂O₃) nanoparticles. TEM images show that shape, size and morphology of the as-prepared products depend on the calcination temperature.

在苯甲酸存在下直接煅烧FeSO 4对煅烧温度对合成产物的形貌，尺寸和结晶相的影响

摘要

在本文中，我们在500和600°C的两个不同温度下，在重量比为1：1的苯甲酸存在下，分解了FeSO ₄。所合成的产物通过傅里叶变换红外（FT-IR）光谱，粉末X射线衍射（XRD）和透射电子显微镜（TEM）进行表征。FT-IR和XRD结果确认了在500℃下所制备的产物是中间体化合物的混合物中，同时在600℃下所制备的产物是具有高度赤铁矿的结晶（α-铁明显纯₂ ö ₃）纳米粒子。TEM图像显示所制备产物的形状，大小和形态取决于煅烧温度。
