Abstract

Abstract: The straightforward co‐precipitation approach was used to effectively manufacture novel silica‐coated magnetic nanoparticles doped with cobalt (Co3 O4 ). These nanoparticles were characterized using Field Emission Scanning Electron Microscopy (FE‐SEM), Energy‐Dispersive X‐ray Spectroscopy (EDS), Wavelength‐Dispersive Spectroscopy (WDX), Powder X‐ray Diffraction Spectroscopy (PXRD), Fourier transform infrared spectroscopy (FT‐IR), Thermo‐gravimetric Analysis (TGA), Inductive coupled plasma‐optical emission spectrometry (ICP‐OES), and Transmission Electron Microscopy (TEM), etc. Intriguingly, the catalytic performance of these nanocrystals for the amines, phenols, alcohols, and thiols acylation processes was examined in solvent‐free conditions, with outstanding yields. These nanoparticles were recycled at least 12 times without losing their catalytic activity. Abstract : In the current study, silica‐coated ferrite nanoparticles supported by cobalt were synthesized and utilized to acylated derivatives of amine, phenol, alcohol, and thiol. The FT‐IR, PXRD, FE‐SEM, EDX, WDX, ICP‐OES, TGA, and TEM methods have been used to investigate the prepared nanoparticles. Interestingly, the nanocatalyst has been recycled a minimum of 12 times with no catalytic loss. The reaction was carried out at room temperature without the need for any solvents, and the catalysts were easy to create and less hazardous.
