One-pot synthesis of MoS2/CoS2 yolk-shell nanospheres

In this work, MoS2/CoS2 yolk-shell nanospheres are synthesized by a one-pot hydrothermal reaction. Furthermore, the yolk-shell spherical morphologies are characterized and confirmed by SEM, TEM characterizations; and the components of CoS2 and MoS2 are investigated by XRD and XPS analysis. It is revealed that the Co precursor and thiourea result in the formation of hollow CoS2 nanospheres, while the Co precursor, Mo precursor and thiourea lead to the fabrication of MoS2/CoS2 yolk-shell nanostructure. The possible growth mechanism of MoS2/CoS2 yolk-shell nanospheres is suggested based on the comparative experiments and characterization of intermediate samples. This research provides a feasible and new strategy to prepare the MoS2/CoS2 hybrid material with yolk-shell architecture. Superscript/Subscript Available
