Stabilization and anchoring of cerium-copper alloy on multi walled carbon nanotube as a superb nanocatalyst: excellent performance in synthetic reactions

Abstract

Here, an environmentally safe structure was developed to stabilize and anchor Ce-Cu alloy nanoparticles on carbon nanotubes, and the synthesis of magnetic nanocatalyst CNT/Fe₃O₄@Ce₃-Cu₂ was studied in the synthesis of dicoumarols and bis-1,3-diethyl thiobarbiturates under stable reaction conditions and ultrasonic irradiation. Our studies showed that magnetic multi-walled carbon nanotubes with porous structures performed well in terms of adsorption of Ce₃–Cu₂ and stabilized the structure of these alloy nanoparticles on magnetic carbon nanotubes, resulting in excellent catalytic activity. It should be noted that ultrasound irradiation causes the alloy electrons of Ce₃–Cu₂ to collide and create a synergistic effect between Ce₃–Cu₂ metals. Our studies proved that the designed magnetic catalyst is recyclable and the high stability of this magnetic bimetallic nanocatalyst provides extensive applications in organic syntheses.
