Abstract

A simple approach was used to create Fe3O4-methylcellulose (MC) nanocomposites, which were then analyzed using XRD, FTIR, and FE-SEM to determine their structure. The effective factors for enhancing the ratio of magnetite NPs in the samples were investigated using RTFM and optical absorbance. Fe3O4 was synthesized utilizing the reverse co-precipitation technique and magnetic characteristics. Fe3O4/MC nanocomposites with magnetite/MC weight ratios of 0, 0.07, 0.15, and 0.25 have been developed. The diffraction pattern of magnetite is well indexed in accordance with the spinal reference pattern of Fe3O4 (space group: R¯3m), as confirmed by the Rietveld analysis of XRD data of magnetite NPs with an average crystallite size of 50 nm. Magnetite’s insertion into the MC network causes a red shift in the band gap energy (Eg) as the weight percentage of magnetite nanoparticles in the samples rises. The MC, MC-7, MC-15, and MC-25 samples have Eg values of 5.51, 5.05, 2.84, and 2.20 eV, respectively.

利用反向共沉淀法合成的新型磁铁矿（Fe3O4）-甲基纤维素纳米复合材料

采用简单的方法制备了 Fe3O4-甲基纤维素（MC）纳米复合材料，然后使用 XRD、FTIR 和 FE-SEM 分析确定了其结构。利用 RTFM 和光学吸光度研究了提高样品中磁铁矿 NPs 比例的有效因素。利用反向共沉淀技术合成了 Fe3O4 并确定了其磁性特征。开发出了磁铁矿/MC 重量比分别为 0、0.07、0.15 和 0.25 的 Fe3O4/MC 纳米复合材料。对平均结晶尺寸为 50 纳米的磁铁矿 NPs 的 XRD 数据进行的里特维尔德分析证实，磁铁矿的衍射图样与 Fe3O4 的脊柱参考图样（空间群：R¯3m）一致。随着样品中磁铁矿纳米粒子重量百分比的增加，磁铁矿插入 MC 网络会导致带隙能（Eg）发生红移。MC、MC-7、MC-15 和 MC-25 样品的 Eg 值分别为 5.51、5.05、2.84 和 2.20 eV。
