Crystallization-induced Self-Hollowing of Molybdenum Sulfide Nanoparticles and Their Potential in Sodium Ion Batteries.

A self-hollowing process was demonstrated for the creation of hollow MoS2 nanospheres starting from their amorphous solid precursor, which were spontaneously transformed into a hollow structure during the rearrangement of crystal lattices initiated by a high-temperature treatment, forming hollow-structured materials favorable for their application in sodium ion batteries.
