Transition metal copper (II) Schiff base composite (Cu-NH₂-GO) was synthesized using functionalized graphene oxide with (3-aminopropyl)methoxysilane (APTMS). X-ray diffraction, FTIR spectroscopy and thermogravimetric analyses ascertained the incorporation of the copper (II) Schiff base on the functionalized graphene oxide. Scanning electron microscopy and TEM evidences further confirmed the surface morphology of the composite. Catalytic activity study indicated that the synthesized Cu-NH₂-GO was active for cross-coupling of aryl halide with phenylboronic acid. Above 84 % (4-Iodobenzonitrile) biphenyl conversion could be achieved using Cu-NH₂-GO heterogeneous catalyst in the C-C coupling reaction. Recovery and reusability study suggests that the catalyst maintains very high conversion for biphenyl (∼80 %, with 4-Bromobenzonitrile) even after being used for four cycles.

使用功能化的氧化石墨烯与（3-氨丙基）甲氧基硅烷（APTMS）合成了过渡金属铜（II）Schiff碱复合材料（Cu-NH ₂ -GO）。X射线衍射，FTIR光谱和热重分析确定了在官能化的氧化石墨烯上掺入席夫铜（II）。扫描电子显微镜和TEM证据进一步证实了复合材料的表面形态。催化活性研究表明，合成的Cu-NH ₂ -GO具有使芳基卤化物与苯基硼酸交叉偶联的活性。使用Cu-NH ₂可以实现84％以上的（4-碘苄腈）联苯转化率-GO多相催化剂在CC偶联反应中。回收率和可重复使用性研究表明，即使在使用四个循环后，该催化剂仍能保持很高的联苯转化率（约80％，带有4-溴苄腈）。
