Synthesis of the Elusive Doublewall Nanotubes and Nanocones(Horns) of MoS ₂ via Focused Solar Ablation

The synthesis of fundamentally small MoS2 nanotubes and nanocones(horns) that have proven elusive in prior studies has been achieved via ablation a precursor mixture crystallites + MoO3 by highly concentrated solar radiation. special far-from-equilibrium conditions the furnace prove conducive to generation these singular nanostructures. Extensive electron microscopy characterization results (transmission (TEM), diffraction (ED), X-ray (XRD), scanning TEM (STEM), high angle annular dark field (HAADF)) reveal range nanoparticle shapes sizes based on which reaction mechanisms are proposed. Molecular dynamics simulations indicate sizable thermal fluctuations intrinsically produced high-temperature reactor soften nanostructures, yielding corrugated layers favor nanostructures with only few layers, agreement experimental observations.
