摘要

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.
