Abstract

Vertical stacking and lateral growth of molybdenum disulfide (MoS₂ ) are controlled with remarkable precision, and MoS₂ nanotubes are directly converted from nanofibers. Predictive synthesis is enabled by identifying the specific thermodynamic region where the Boudouard reaction becomes favored. It reveals how the chemical potential of each species in the MoSCO system can predict phase behaviors.

Keywords: molybdenum disulfide; nanoscale Boudouard reaction; predictive synthesis; selective oxidation; spontaneous assembly.
