A 3D graphene architecture can be prepared via an in situ self‐assembly of graphene prepared by a mild chemical reduction. Fe 3 O 4 nanoparticles are homogeneously dispersed into graphene oxide (GO) aqueous suspension and a 3D magnetic graphene/Fe 3 O 4 aerogel is prepared during the reduction of GO to graphene. This provides a general method to prepare 3D graphene/nanoparticle composites for a wide range of applications including catalysis and energy conversion.
