Abstract This paper reports the synthesize of M-Type substituted Strontium hexaferrite via chemical coprecipitation technique in aqueous solution. Moreover, MB degradation by Sr(CeNd)x Fe12-2xO19 (SCNH)(x=0.2) and polymerized Sr(CeNd)xFe12-2xO19/polythiophene (SCNH/PTh) (x=0.2) with two stichometry amount (1:1, 1:2) was studied. For more characterization, the FTIR spectrum and X-ray diffractometer represent the pure phase and the structure of aimed nanoparticles while confirm polymerization took place. The hexagonal structure of prepared samples has shown by Surface images of FESEM, the micrographs illuminate, polymer-coated the plate-like hexaferrite which approves polymerization was complete. Hysteresis loops of SCNH and SCNH/PTh depict that they possess magnetic properties that are helpful for magnetical collection from water solution. The photodegradation activity of prepared photocatalysts studied under Uv-vis light. According to data SCNH/PTH (1:2) represented the best photocatalysis degradation ability by 98%. The photodegradation kinetic curve approved that photocatalysis activity obeys first order. The reusability of prepared samples was measured in 3 times repeated experiment and shows although their capability decreased to 89% in SCNH/PTh (1:2), it illuminates acceptable photodegradation ability as well.

Sr(CeNd)xFe12-2xO19/聚噻吩纳米颗粒：结构研究、磁性和光催化活性

摘要 本文报道了在水溶液中通过化学共沉淀技术合成M型取代的六铁酸锶。此外，MB 被 Sr(CeNd)x Fe12-2xO19 (SCNH)(x=0.2) 和聚合 Sr(CeNd)xFe12-2xO19/聚噻吩 (SCNH/PTh) (x=0.2) 以两种化学计量（1:1）降解, 1:2) 进行了研究。对于更多表征，FTIR 光谱和 X 射线衍射仪代表纯相和目标纳米颗粒的结构，同时确认聚合发生。所制备样品的六边形结构经FESEM表面图像显示，显微照片照亮，聚合物包覆的板状六铁氧体表明聚合完成。SCNH 和 SCNH/PTh 的磁滞回线表明它们具有有助于从水溶液中收集磁性的磁性。在紫外-可见光下研究制备的光催化剂的光降解活性。根据数据，SCNH/PTH (1:2) 代表了 98% 的最佳光催化降解能力。光降解动力学曲线证实光催化活性服从一阶。在 3 次重复实验中测量了制备样品的可重复使用性，表明尽管它们在 SCNH/PTh (1:2) 中的能力下降到 89%，但它也说明了可接受的光降解能力。
