| 摘 要： | 研究了以水滑石为载体原位负载贵金属纳米颗粒(Pd、Ag、Ru、Au)的方法,通过共沉淀合成甲酸根水滑石,以层间甲酸根为还原剂原位还原贵金属前驱体制得高分散水滑石(LDH)负载纳米颗粒。本方法无需载体预处理,操作方便、适用性强,阴离子前驱体(Au)和阳离子前驱体(Pd、Ag、Ru)均可顺利得到纳米颗粒。所得水滑石负载纳米颗粒系一种潜在的纳米催化剂,作为示例,Pd/LDH在Suzuki偶联反应中显示出较高催化活性。

| Abstract: | A facile method was developed for reductive loading of well-dispersed noble metal nanoparticles (Pd, Ag, Ru and Au) on layered double hydroxide (LDH). It involves the preparation of formate-LDH by coprecipitation and the subsequent in situ reduction of noble metal precursors by interlayer formate anion. Nanoparticles from both anionic (Au) and cationic (Pd, Ag, Ru) precursors could be loaded successfully, demonstrating the feasibility of this method. In addition, as an example, the obtained Pd/LDH showed good activity for Suzuki cross-coupling reaction, suggesting potential catalytical application of prepared composites. |
