摘要
Graphene-Fe3O4 nanocomposite（G-Fe3O4） was synthesized by a chemical co-precipitation method which was used as an efficient catalyst for the reduction of nitroarenes with hydrazine hydrate.The method has been applied to a broad range of compounds with different properties and the yields were in the range of 75%-92%.The G-Fe3O4 catalyst can be readily recovered and reused 5 times without significant loss of the catalytic activity.
