Ag(2)CO(3) containing magnetic nanocomposite as a powerful and recoverable catalyst for Knoevenagel condensation

In this paper, the synthesis, characterization and catalytic application of a novel magnetic silica-supported Ag(2)CO(3) (MS/Ag(2)CO(3)) with core–shell structure are developed. The MS/Ag(2)CO(3) nanocomposite was prepared through chemical modification of magnetic MS nanoparticles with AgNO(3) under...

description In this paper, the synthesis, characterization and catalytic application of a novel magnetic silica-supported Ag(2)CO(3) (MS/Ag(2)CO(3)) with core–shell structure are developed. The MS/Ag(2)CO(3) nanocomposite was prepared through chemical modification of magnetic MS nanoparticles with AgNO(3) under alkaline conditions. The structure, chemical composition and magnetic properties of MS/Ag(2)CO(3) were investigated by using VSM, PXRD, FT-IR, EDX and SEM techniques. The MS/Ag(2)CO(3) nanocomposite was used as an effective catalyst for the Knoevenagel condensation under solvent-free conditions at 60 °C in an ultrasonic bath. The recovery and leaching tests were performed to study the nature of the MS/Ag(2)CO(3) catalyst under applied conditions.
