▎ 摘 要
Pd nanoparticles were immobilized on a graphene oxide(GO) functionalized by 3-(2-aminoethyl)-aminopropyl trimethoxysilane support. The catalyst was characterized by Fourier transform infrared (FTIR), X-ray diffraction, thermal analysis, elementary analysis, and transmission electron microscopy. The catalyst exhibited a superior catalytic performance in Heck coupling reaction, and was applicable to a wide range of substrates. Recycling experiments showed that the catalyst could be easily recovered by simple centrifugation and reused for up to three cycles without losing its activity.
