Abstract In this work, Material of Institute Lavoisier-53(Fe) (MIL-53(Fe)) with four morphologies were prepared, using Fe3O4 as precursor and adjusting the amount of hydrochloric acid during the production process. The morphology characteristics and composition of MIL-53(Fe) were investigated by scanning electron microscope, energy disperse spectroscopy, X-ray diffraction, infrared spectrometer and N2 absorption-desorption, demonstrating MIL-53(Fe) with different morphologies were successfully synthesized. Besides, the Fe2O3 was appearing with the increasing volume of hydrochloric acid. The results of electrochemical experiments showed that the fusiform structured MIL-53(Fe)/Fe2O3 had better electrochemical properties towards hydrazine oxidation at 0.85 V with a detection limit of 0.03 μM and rapid response time within 3 s. In addition, the two linear ranges were 0.25–380 μM and 380–8400 μM with sensitivities of 212.2 and 61.92 μA mM−1 cm−2 separately.

用于安培法测定肼的 Lavoisier-53(Fe) 研究所材料的受控合成

摘要 本研究以Fe3O4为前驱体,在生产过程中调节盐酸用量,制备了四种形貌的Lavoisier-53(Fe)材料(MIL-53(Fe))。通过扫描电子显微镜、能量色散谱、X射线衍射、红外光谱仪和N2吸脱附对MIL-53(Fe)的形貌特征和组成进行了研究,证明了不同形貌的MIL-53(Fe)被成功合成。此外,Fe2O3 随盐酸体积的增加而出现。电化学实验结果表明,梭形结构的 MIL-53(Fe)/Fe2O3 在 0.85 V 下对肼氧化具有更好的电化学性能,检测限为 0.03 μM,响应时间在 3 s 内。此外,
