Symmetry-broken MoS₂ nanotubes through sequential sulfurization of MoO₂ nanowires.

ABSTRACT: Transition metal dichalcogenide (TMD) nanotubes are emerging quantum materials with distinctive symmetry-breaking properties, offering significant potential for energy conversion technologies. However, the direct synthesis of crystalline MoS₂ nanotubes remains challenging due to limited understanding of their high-temperature growth mechanisms. Here, we present a robust and controllable strategy for the direct growth of crystalline MoS₂ nanotubes with well-defined tubular morphology and high structural uniformity. This approach features two key innovations: first, the controlled introduction of hydrogen reduces MoO₃ into one-dimensional (1D) tetragonal MoO₂ (space group I4/m) chains via a vapor-liquid-solid (VLS) mechanism; second, precise temper
