Hydrophilic Fe3O4/C nanocomposites have been prepared by a simple one-step hydrothermal reaction route, and demonstrated a high Cr(vi) removal capacity.
We demonstrate a facile one-step hydrothermal strategy to build a nanostructure of α-Fe2O3 nanoplates imbedded in graphene networks with high rate lithium storage and long cycle life as anode material.
