Robust nanocomposites of a-Fe2O3 and N-doped graphene oxide: Interfacial bonding and chemisorption of H₂O...

In this work, hematite microdisks (500 nm to 1 μm in diameter, ∼200 nm in thickness) have been synthesized by a facile hydrothermal method which exhibited good cycling stability at a current density of 200 mA g−1 and 1000 mA g−1, and excellent rate performance at various current densities ranging fr...
