Coordinated assembly of a new 3D mesoporous Fe3O4@Cu2O–graphene oxide framework as a highly efficient and reusable catalyst for the synthesis of quinoxalines

Abstract

A new three-dimensional (3D) mesoporous hybrid framework was synthesized by coordinated layer-by-layer assembly between nanosheets of reduced graphene oxide and Fe₃O₄@Cu₂O. This 3D mesoporous framework shows an excellent catalytic performance with a remarkable activity, selectivity (>99%), and strong durability in the synthesis of quinoxalines.
