中文摘要:
      采用离子交换和共沉淀两步法合成了氧化石墨烯-四氧化三铁复合物(GO-Fe3O4),并负载钯(Pd)纳米颗粒得到了催化剂Fe3O4-GO-Pd。用SEM和FTIR对其表面形貌和组成进行了表征。160 ℃下,以N,N-二甲基甲酰胺(DMF)为溶剂,将该催化剂用于溴苯和丙烯酸酯的Heck偶合反应中,产率可达98.64 %,且连续使用4次后,产率仍可保持97.51 %。
英文摘要:
      In this paper, graphene oxide-ferroferric oxide (GO-Fe3O4) composite was synthesized by a two-step process consisting of ion-exchange and coprecipitation and then it was deposited with palladium nanoparticles to obtain the lamellar catalyst Fe3O4-GO-Pd. The composition and structure were confirmed by XRD and SEM. The Heck reaction of bromobenzene and acrylic ester by the catalyst Fe3O4-GO-Pd were studied and the results showed that the yield can be 98.64% at 160℃ when performed with N,N-dimethylformamide (DMF) as solvent and it can still be 97.51% even after 4 recycling use.
