Synthesis of Pd@PdNi-Ti-EG Nano-catalyst and High Catalytic Performance in Suzuki-Miyaura Reaction
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.
