摘要

本研究采用浸渍法在赤铁矿表面合成了尖晶石钴和铜铁氧体纳米颗粒。用FTIR、XRF、XRD、FESEM、BET和EDS对合成的粉末进行了表征和检测，并用UV-vis和AAS方法研究了染料的降解。比表面积增加，尤其是在含有钴的样品中，这表明合成的精确性和在赤铁矿表面产生的高表面纳米颗粒。颗粒大小为纳米级，在结构中观察到良好的均匀性。结果表明，赤铁矿纳米复合材料的催化能力显著提高。通过紫外-可见光照射从溶液中完全去除亚甲基蓝的Fenton反应研究了它们的催化能力。通过原子吸收光谱法发现样品的稳定性非常好。

Synthesis and Characterization of CoFe2O4 and CuFe2O4 Composited with Hematite by Impregnation Method for Removing Organic Pollutants

In this research, using impregnation method, spinel cobalt and copper ferrites nanoparticles are synthesized on the surface of hematite. Synthesized powders were characterized and examined by FTIR, XRF, XRD, FESEM, BET and EDS analysis and the dye degradation was investigated by UV-vis and AAS methods. Specific surface area increased especially in the sample containing cobalt, which indicates the precise of synthesis and the creation of high surface nanoparticles at hematite surface. The size of particles was in the nano scale and a good uniformity observed in the structure. The results indicated a significant increase in the catalytic ability of hematite nanocomposite. Their catalytic capability investigated by the Fenton reaction with complete removal of methylene blue from the solution via UV-vis irradiation. The samples stability discovered to be excellent by the AAS method.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
