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

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 MoO2@CoO-CoMoO4-NC hybrid nanorods have been successfully synthesized. Benefiting from the unique morphology, structure and components, the MoO2@CoO-CoMoO4-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 MoO2@CoO-CoMoO4-NC hybrid nanorods could be very promising anode materials for LIBs. (C) 2019 Elsevier B.V. All rights reserved.
