چکیده مقاله
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/HTSH-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.
