Abstract

The FeS nanoparticles have been synthesized from thioacetamide and ferric chloride by hydrothermal method, and the as-prepared nanoparticles have been characterized by X-ray diffraction, scanning electron microscopy, energy dispersive spectrometry and AC impedance spectrometry. Electrochemical reduction of 2,4-dinitrochlorobenzene at nano FeS-modified glassy carbon electrode is investigated, and the results indicating that the FeS have a certain catalytic effect on 2,4-dinitrochlorobenzene reduction. The reaction mechanism is also discussed.

FeS纳米粒子的合成催化还原2,4-二硝基氯苯

摘要

通过水热法由硫代乙酰胺和氯化铁合成了FeS纳米颗粒，并通过X射线衍射，扫描电子显微镜，能量色散谱和交流阻抗谱对制备的纳米颗粒进行了表征。研究了纳米FeS修饰的玻碳电极上2,4-二硝基氯苯的电化学还原反应，结果表明FeS对2,4-二硝基氯苯还原具有一定的催化作用。还讨论了反应机理。
