Heterostructures have diverse physicochemical properties and functions due to synergistic effects and interfacial interactions. This study developed a facile in situ localized phase transformation strategy to create MoO2@MoS2 heterostructures for superior sodium storage performance. The MoO2@MoS2/rGO electrode exhibited distinguished reversible capacity and remarkable rate performance, providing a simple method for constructing stable heterostructures for high-performance energy storage materials.
Heterostructures have gained intensive attentions in various energy storage fields due to their diverse physicochemical properties and functions, originating from the synergistic effects and interfacial interaction between the different components. However, it is still a great challenge to employ simple methods to design an advanced heterostructure for superior sodium storage performances. Herein, a facile in situ localized phase transformation strategy has been developed to transfer MoO3 nanoparticles anchored on rGO nanosheets into MoO2@MoS2 heterostructures (MoO2@MoS2/rGO). Benefiting from faster ion transport at the heterogeneous interface, higher conductivity as well as more active sites for Na storage than that of single component, MoO2@MoS2/rGO electrode exhibits distinguished reversible capacity (604.1 mAh g(-1) at 0.1 A g(-1)) and remarkable rate performance (420.8 mAh g(-1) at 5.0 A g(-1)) when evaluated as an anode for SIBs. This work provides a simple and feasible method for constructing stable heterostructures for high-performance energy storage materials. (C) 2021 Elsevier Ltd. All rights reserved.
