Metal-organic framework-engaged synthesis of multicomponent MoO2@CoO-CoMoO4-NC hybrid nanorods as promising anode materials for lithium-ion batteries

Abstract Developing facile strategies to synthesize transition metal oxides and nitrogen-doped carbon (NC) hybrid materials is important for lithium-ion batteries (LIBs) but also challenging. Herein, unique one-dimensional multicomponent MoO 2 @CoO-CoMoO 4 -NC hybrid nanorods have been successfully synthesized. Benefiting from the unique morphology, structure and components, the MoO 2 @CoO-CoMoO 4 -NC hybrid nanorods exhibit a high reversible discharge capacity of 1164.0 mA h g −1 at 200 mA g −1 for 80 cycles, good rate performance (394.5 mA h g −1 at 4000 mA g −1 ) and cycling stability (688.8 mA h g −1 at 1000 mA g −1 for 350 cycles). It is believed that the MoO 2 @CoO-CoMoO 4 -NC hybrid nanorods could be very promising anode materials for LIBs.
