Abstract

In this research, a novel Schiff-base/palladium complex containing magnetic ordered mesoporous silica (Fe3O4@MCM-41-SB/Pd) material with a core–shell structure is prepared and characterized, and its catalytic application is developed. The Fe3O4@MCM-41-SB/Pd nanocatalyst was characterized using FT-IR, TGA, SEM, VSM, PXRD and energy-dispersive X-ray (EDX) spectroscopy. This nanocatalyst showed high performance in the Suzuki cross-coupling reaction under ultrasonic conditions and delivered the corresponding products in high to excellent yield. The recovery study of the nanocatalyst proved that its activity is maintained during several stages of reuse. Moreover, the high stability of palladium species on the core–shell surface was confirmed by leaching and poisoning tests.
