Pd@PdNi-Ti-EG纳米催化剂的制备及催化Suzuki-Miyaura反应OA
Synthesis of Pd@PdNi-Ti-EG Nano-catalyst and High Catalytic Performance in Suzuki-Miyaura Reaction
以简单易行的方法制备了一种新型的高度分散的 Pd@PdNi-Ti-EG 非均相纳米催化剂,并通过 XRD、SEM、TEM、XPS、ICP等仪器分析技术对其进行了形貌表征,并把该催化剂应用于Suzuki-Miyaura交叉偶联反应.结果表明:纳米钯颗粒均匀分布于棒状PdNi-Ti-EG介孔结构表面,颗粒尺寸小于 10 nm;以环境友好的乙醇/水为反应溶剂,此催化剂在Suzuki-Miyaura交叉偶联反应中表现出极好的催化活性和官能团兼容性,经 15 次回收后,未见催化活性的明显降低,显示出极好的可回收性.
A new and highly dispersed Pd@PdNi-Ti-EG heterogeneous nano-catalyst was conveniently prepared via a simple procedure.The obtained Pd@PdNi-Ti-EG nano-particle was well characterized by several physicochemical techniques,such as XRD,SEM,TEM,XPS,ICP and so on.Subsquently,this Pd@PdNi-Ti-EG nano-particle was served as the catalyst of Suzuki-Miyaura cross-coupling reaction.It was found that,with environmentally friendly ethanol/water as the reaction solvent,this catalyst showed excellent catalytic activity and functional group compatibility.Moreover,this nano-catalyst exhibited excellent recyclability that up to 15 recyclings showed no significant reduction in catalytic activity.
