We aimed to immobilize a complex of iron(III) amine bis(phenolate) on silica‐coated magnetic nanoparticles as a new magnetically recoverable catalyst (Fe₃O₄@SiO₂‐APTES‐FeL^GDC). Both the chemical nature and the structure of catalyst were confirmed by using field‐emission transmission electron microscopy, field‐emission scanning electron microscopy, FTIR spectroscopy, thermogravimetric analysis, vibrating sample magnetometry, X‐ray photoelectron spectroscopy, XRD, atomic absorption spectroscopy, and elemental analysis. This sustainable catalyst leads to the efficient oxidation of a wide range of alcohols and sulfides with excellent conversion and selectivity under a mild conditions to their corresponding oxidized products, acids (or ketones) and sulfoxides, respectively. Furthermore, the stability of the structure and morphology of our efficient recyclable system was investigated, and all of the data proved that the complex was anchored firmly to the magnetite nanoparticles.

固定在二氧化硅包覆的磁性纳米粒子上的铁（III）胺双（酚盐）络合物：一种高效的氧化醇和硫化物的催化剂

我们旨在将铁（III）胺双（酚盐）络合物固定在二氧化硅包覆的磁性纳米颗粒上，作为一种新型的可磁回收催化剂（Fe ₃ O ₄ @SiO ₂ -APTES-FeL ^GDC）。催化剂的化学性质和结构均通过场发射透射电子显微镜，场发射扫描电子显微镜，FTIR光谱，热重分析，振动样品磁力分析，X射线光电子能谱，XRD，原子吸收光谱和元素分析。这种可持续的催化剂可在温和条件下将多种醇和硫化物有效氧化，并具有出色的转化率和选择性，分别氧化成其相应的氧化产物，酸（或酮）和亚砜。此外，研究了我们有效的可循环利用系统的结构和形态的稳定性，所有数据均证明该复合物牢固地锚定在磁铁矿纳米颗粒上。
