Abstract
The removal of metals from chemical reactions has raised growing concerns for conserving
natural resources and environmental safety. Therefore, it is necessary to expand simple procedures
that use eco-friendly materials with high elimination capacities. In this paper, we have
synthesized a new nanocomposite material in which eggshell membranes act as nucleation sites
for CoFe2O4 nanoparticle precipitation in the attendance of an external magnetic field. In the next
step anchoring a chlorosulfonic acid on the surface of eggshell-coated magnetic nanoparticles as
solid waste was transformed into a magnetic biomaterial, green, cheap, and environmentally
friendly catalyst (CoFe2O4@Eggshell@SO3H). Techniques such as FT-IR, VSM, FESEM, TEM,
EDX, XRD, and TGA were used to characterize the as-synthesized catalyst. The catalytic property
of the as-prepared catalyst was examined in the synthesis of 2,4,6-triarylpyridine, b-aminocarbonyl,
and 2-amino-4,6-diphenylnicotinonitrile via alcohol-based oxidation. Excessive yield, quick reaction
time, solvent-free condition, waste to wealth, and optimization with the layout of the experiment
are the important advantages of the present work. Taken collectively, these results offer the
conversion of wastage to fortune products around the world and utilization in organic metamorphosis.
