Ruthenium nanoparticles (RuNPs) were prepared through the hydrogenation of [Ru(COD)(COT)] (COD = 1,5-cyclooctadiene, COT = 1,3,5-cyclooctatriene) in the presence of diphosphites derived from carbohydrates as stabilizing agents, and interestingly, structural modifications of the diphosphite backbone were found to influence nanoparticle size and dispersity, as well as their catalytic activity in arene hydrogenation.
通过在源自碳水化合物的二亚磷酸酯作为稳定剂存在的条件下,对[Ru(COD)(COT)](COD = 1,5-环辛二烯,COT = 1,3,5-环辛三烯)进行氢化反应制备了钌纳米颗粒(RuNPs),有趣的是,发现二亚磷酸酯主链的结构修饰会影响纳米颗粒的尺寸和分散性,以及它们在芳烃氢化反应中的催化活性。
