Abstract: Abstract Structure-tuned Fe3O4 and graphene composites were prepared using a facile graphene/acid assisted facile one-pot hydrothermal method. The structural characteristics of Fe3O4 can be tuned by adjusting the initial molar ratio between iron acetylacetonate and citric acid. The citric acid serves dual function as a reducing agent during the production of Fe3O4 nanoparticles (NPs), and as a bridging agent which under optimized conditions can result in mesoporous Fe3O4 nanospheres (NSs) self-assembled by numerous Fe3O4 NPs. The fabricated mesoporous Fe3O4 NSs and graphene composites were evaluated as potential anode materials for lithium ion batteries. These composites exhibit better electrochemical performance with high reversible capacity, good rate capability and cyclic stability derived from their unique mesoporous structural features.
