Graphene oxide supported copper coordinated amino acids as novel heterogeneous catalysts for epoxidation of norbornene


In this work, we explored whether graphene oxide after modification with copper coordinated amino acids could attain an excellent catalytic activity for the epoxidation of norbornene. Therefore, graphene oxide sheets were functionalized with different amino acids through coordination to copper ions for the synthesis of copper coordinated amino acids-grafted graphene oxide. For this aim, at first amino acids were coordinated to Cu2 +. Then, copper ions were complexed with GO. The catalytic activity of the prepared novel catalysts were tested in epoxidation of norbornene. These catalysts showed excellent catalytic performance compared with reported catalysts in other works which demonstrated graphene oxide as a support is superior to other support materials.
