Abstract The present work reports on the structural and magnetic properties of TiO2 P25 Degussa powder doped with cobalt. Dissolution of cobalt in TiO2 matrix was achieved by precipitation of tris(diethyldithiocarbamato) cobalt(III) (CoDtc - Co[S2CN(C2H5)2]3 in chloroform (CHCl3) and consequent thermal treatment. Five different Co atomic percentage contents were chosen, e.g., 0.5%, 1%, 2%, 5% and 10%. It was shown that cobalt atoms are uniformly distributed across TiO2 matrix and exhibit antiferromagnetic interactions at low temperatures.

Co掺杂P25 TiO2纳米粒子的结构和磁性

摘要 目前的工作报告了掺杂钴的 TiO2 P25 Degussa 粉末的结构和磁性能。钴在 TiO2 基质中的溶解是通过在氯仿 (CHCl3) 中沉淀三（二乙基二硫代氨基甲酸）钴 (III) (CoDtc - Co[S2CN(C2H5)2]3 并随后进行热处理来实现的。选择了五种不同的 Co 原子百分比含量，例如，0.5%、1%、2%、5% 和 10% 表明钴原子均匀分布在 TiO2 基体上，并在低温下表现出反铁磁相互作用。
