The hybrid is synthesized by one-step hydrothermal method but exhibits excellent lithium and sodium storage performances. The as-synthesized Co3S4/CoMo2S4@rGO presents reversible capacity of 595.4 mA·h·g-1 and 408.8 mA·h·g-1 after 100 cycles at a current density of 0.2 A·g-1 for lithium and sodium ion storages, respectively. Such superior performances are attributed to the unique composition and structure of Co3S4/CoMo2S4@rGO. The rGO provides a good electronically conductive network and ensures the formation of spinel Co3S4/CoMo2S4 nanoparticles, the Co3S4/CoMo2S4 nanoparticles provide large reaction surface for lithium and sodium intercalation/deintercalation, and the spinel structure allows fast lithium and sodium ion diffusion in three dimensions.
