Abstract

Ferrite chromite (FeCr2O4) powders have been synthesized by a hydrothermal method using various alkaline agents and capping agent. For the first time, nanostructured Ferrite chromite was synthesized with utilizing tetraethylenepantamine as a new alkaline agent. The SDS, PVP and PEG as stabilization agent and capping agent in presence of TEPA as alkaline agent were employed to prepare of the Ferrite chromite. The structural character of as-synthesized powders was characterized by X-ray diffraction (XRD), scanning electron microscope (SEM) and energy dispersive X-ray microanalysis (EDX). The results indicate that the as-obtained powders are pure. The electronic properties of as-synthesized powders was characterized by UV–Vis diffuse reflectance analysis (DRS), which shows the as-obtained sample has a significant absorption in the UV region. The photocatalytic degradation of the rhodamine B, methyl orange, murexide and methylene blue as water pollutants were investigated. According to the results, photocatalytic activity of FeCr2O4/Ag nanostructures were better than of other samples and degradation percent of rhodamine B as a cationic pollutant was more than the other dyes.

FeCr2O4和FeCr2O4/Ag纳米复合材料的合成、表征及其光催化活性

采用水热法，用各种碱性试剂和封端剂合成了铬酸铁氧体（FeCr2O4）粉末。以四亚乙基五胺为新型碱性试剂，首次合成了纳米铁氧体亚铬铁矿。以十二烷基硫酸钠（SDS）、聚乙烯吡咯烷酮（PVP）和聚乙二醇（PEG）为稳定剂，在三元乙丙橡胶（TEPA）为碱性试剂的条件下，制备了亚铬酸铁氧体。用X射线衍射仪（XRD）、扫描电子显微镜（SEM）和能谱仪（EDX）对合成的粉末的结构特征进行了表征。结果表明，所得粉末是纯的。通过紫外-可见漫反射分析（DRS）对合成粉末的电子性能进行了表征，表明所获得的样品在紫外区域具有显著的吸收。研究了罗丹明B、甲基橙、紫外和亚甲基蓝等水污染物的光催化降解性能。结果表明，FeCr2O4/Ag纳米结构的光催化活性优于其他样品，阳离子污染物罗丹明B的降解率高于其他染料。
