Dimensionality engineering and novel synthesis of Bi2O2Te nanowires from their 2D nanoplates.

• Bi 2 O 2 Te nanowires were grown via Au-catalyzed vapor–liquid-solid, solving challenge of fabricating 1D Bi 2 O 2 Te. • Growth of Bi 2 O 2 Te nanowires is influenced by crystal structure, Au nanoparticle distribution and liquid–solid interface dynamics. • This process transitions 2D Bi 2 O 2 Te to 1D and can unlock new properties. To address the growing demand for high-performance 1D nanostructured semiconductors, this study reports on the directional growth of Bi 2 O 2 Te nanowires facilitated by a Au nanoparticle-catalyzed vapor–liquid–solid (VLS) process. We reveal how the growth of Bi 2 O 2 Te nanowires is directionally influenced by the crystallographic orientation of the material and the dynamics at the liquid–solid interface, presenting the process's ability to transition the intrinsic properties of 2D materials into 1D nanostructures.
