摘要：

The morphology and hybridization of nanostructures are crucial to achieve properties for various applications. An in situ grown three-dimensional (3D) MoS2 nanomask has been adopted to control the morphology and hybridization of molybdenum compounds. The in situ generated MoS2 mask on MoO3 nanobelt surfaces allowed us to fabricate a 3D c-MoO2@MoS2 hybrid nanostructure, in which c-MoO2 is a carved MoO2 nanobelt with a well-distributed hole pattern. The nanomasks have been controlled by adjusting the alignments of MoS2. The exposed MoO2 surfaces of c-MoO(2)gMoS(2) were further sulfurated to give cw-MoO2@MoS2, in which all surfaces of MoO2 are wrapped by a few layers of MoS2. The structure synergistically enhanced the electrochemical performances of MoO2 and MoS2, especially at high current rates. Reversible capacities of 1418 and 295 mAh/g after 115 and 300 cycles still remained for the cw-MoO2@MoS2 anodes at current rates of 1 and 10 A/g, respectively.
