Abstract

A green and economical catalyst should have certain characteristics such as low preparation cost, high activity, excellent selectivity, high stability, simple separation and good recyclability. One of the important issues in catalysis that has been considered in recent years is the immobilization of transition metal complexes on the surface of magnetic nanoparticles. Magnetic nanocatalysts are easily separated from the reaction mixture through an external magnetic field. Amongst transition metals, silver (Ag) has a special place in catalyst science. During the last decade, preparation and silver complexes stabilized on the surface of magnetic nanoparticles and their applications as catalyst in various organic reactions such as coupling, oxidation, reduction and multicomponent reactions. In this review, we discussed on MNPs-Ag catalysts and their activity in chemical reactions.

摘要

一种绿色经济的催化剂应具有某些特点，例如制备成本低，活性高，选择性好，稳定性高，分离简单和可回收性好。近年来已考虑的重要催化问题之一是过渡金属络合物在磁性纳米颗粒表面的固定化。磁性纳米催化剂易于通过外部磁场与反应混合物分离。在过渡金属中，银（Ag）在催化剂科学中占有特殊的地位。在过去的十年中，制备物和银络合物稳定在磁性纳米颗粒的表面上，并在各种有机反应（例如偶联，氧化，还原和多组分反应）中作为催化剂应用。在这篇评论中，
