Abstract Hydrotalcite (HT) modified with magnetic nanoparticle and thiol groups for the immobilization of silver to the preparation of Fe3O4/HT-SH-Ag was used. The catalyst was completely characterized using XRD, ICP, SEM, EDS, VSM, FT-IR, and TEM analyzes. The Fe3O4/HT-SH-Ag catalyst is useful in oxidizing of primary and secondary aliphatic and benzyl alcohols to the relevant carbonyl products (aldehyde/ketone). To demonstrate the effect of Ag over the reaction, Fe3O4/HT-SH catalyst performance, and also some other control tests were studied. For this purpose, the model reaction was carried out in the presence of AgNO3, HT (I), and Fe3O4/HT (II), and low yield was obtained (20–50%). High to good efficiency were obtained for all entries, whether benzaldehyde derivatives, in short times. The catalyst can be reused for several continuous runs with a simple external magnet without losing significant reactivity.

固定在功能化磁性水滑石 (Fe3O4/HT-SH-Ag) 上的 Ag 纳米颗粒用于使用 TBHP 清洁氧化醇

摘要 使用磁性纳米粒子和硫醇基团修饰的水滑石 (HT) 将银固定在 Fe3O4/HT-SH-Ag 的制备中。使用 XRD、ICP、SEM、EDS、VSM、FT-IR 和 TEM 分析对催化剂进行了完整表征。Fe3O4/HT-SH-Ag 催化剂可用于将脂肪族伯醇和仲醇氧化成相关的羰基产物（醛/酮）。为了证明 Ag 对反应的影响，研究了 Fe3O4/HT-SH 催化剂的性能以及一些其他控制测试。为此，模型反应在 AgNO3、HT (I) 和 Fe3O4/HT (II) 存在下进行，但收率较低（20-50%）。所有条目，无论是苯甲醛衍生物，都在短时间内获得了高到良好的效率。
