Graphene@nitrogen doped carbon@ultrafine TiO2 nanoparticles (G-NC@TiO2) with porous structure are obtained through annealing the precursor of graphene oxide/metal-organic frameworks (MOFs) for the first time. As an anode material for sodium ion batteries (SIB), the G-NC@TiO2 composite can deliver an excellent capacity retention of 93% even after 5000 cycles, and a superior rate capability.
