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.
