Fe₃O₄@SiO₂-PMA-Cu magnetic nanoparticles as a novel catalyst for green synthesis of β-thiol-1,4-disubstituted-1,2,3-triazoles.

ABSTRACT: The magnetic nanoparticles of Fe₃O₄ were synthesized through a solid-state reaction of hydrated iron (III) chloride, hydrated iron (II) chloride and NaOH, and then purified by calcination at high temperature. In order to protect ferrite nanoparticles from oxidation and agglomeration, and to manufacture a novel catalytic system of anchored copper on the magnetic substrate, the Fe₃O₄ was core-shelled by adding tetraethyl orthosilicate. Next, the prepared Fe₃O₄@SiO₂ was supported by phosphomolybdic acid (PMA) as the second layer of nanocomposite at 80 °C in 30 h. Eventually, the new nanocomposite of Fe₃O₄@SiO₂-PMA-Cu was successfully synthesized by adding copper (II) chloride solution
