The primary objective of this investigation was to develop a new nanocatalyst that could produce amides by oxidative amidation of benzyl alcohol, thereby reducing its environmental harm. To achieve this, Pd nanoparticle-immobilized crosslinked sodium alginate-modified iron-based metal-organic framework Fe(BTC) (Fe(BTC)@SA/ED/Pd), with excellent activity and selectivity in modified oxidative amidation of benzyl alcohol with amines, has been described. Crosslinked sodium alginate was modified on iron-based metal-organic framework Fe(BTC). It is worth noting that Pd nanoparticles were immobilized for the first time on a novel nanocomposite based on the Fe(BTC) MOF and crosslinked sodium alginate for tandem oxidative amidation to improve the eco-friendliness and economic efficiency of the process. The synergic effects of Fe(BTC), sodium alginate, and Pd NPs are important factors influencing the catalytic activity. Easy and green synthesis methods, availability of materials, high Pd loading, available catalytic sites, high surface area, high selectivity, and simple separation from the reaction medium are effective properties in catalytic activity.
本研究的主要目的是开发一种新型纳米催化剂,该催化剂可通过苄醇的氧化酰胺化反应生成酰胺,从而减少其对环境的危害。为实现这一目标,已报道了一种钯纳米颗粒固定化的交联海藻酸钠改性铁基金属有机框架Fe(BTC)(Fe(BTC)@SA/ED/Pd),其在苄醇与胺的改性氧化酰胺化反应中具有优异的活性和选择性。交联海藻酸钠在铁基金属有机框架Fe(BTC)上进行了改性。值得注意的是,钯纳米颗粒首次固定在基于Fe(BTC)金属有机框架和交联海藻酸钠的新型纳米复合材料上,用于串联氧化酰胺化反应,以提高该过程的生态友好性和经济效率。Fe(BTC)、海藻酸钠和钯纳米颗粒的协同效应是影响催化活性的重要因素。简便绿色的合成方法、材料的可得性、高钯负载量、可用的催化位点、高比表面积、高选择性以及与反应介质的简单分离是催化活性方面的有效特性。
