Robust iron-on-graphene catalyst The cover picture shows highly dispersed iron oxide nanoparticles anchored on reduced graphene oxide (rGO) with defects. In their Communication on p. 714 ff., B. Sun et al. demonstrate the one-pot fabrication of such materials using different metal acetylacetonates and GO as starting materials. The outstanding stability of the small iron oxide nanoparticles on rGO is validated in high-temperature reduction and in long-term gas-phase Fischer-Tropsch synthesis. This work presents the promising future of the graphene-related nanomaterials, even in very challenging high-temperature applications by facile materials design.
