MoS2 Hybrid nanostructures: From octahedral to quasi-spherical shells within individual nanoparticles Academic Article uri icon

abstract

  • MoS2, a layered compound with tribological and catalytic applications, is known to form a range of hollow closed nanostructures [1–5] and nanoparticles, including graphene-like structures.[6] These have been demonstrated experimentally through high-temperature synthesis and pulsed laser ablation (PLA), and theoretically with quantum chemical calculations. The smallest allowed structures are nanooctahedra of 3 to 8nm size. Nicknamed the “true inorganic fullerene” in analogy to carbon fullerenes,[4] they differ from larger multiwalled MoS2 fullerene-like nanoparticles both in their morphology and predicted electronic properties. The larger fullerene-like particles are quasi-spherical (polyhedral) or nanotubular, typically with diameters of 20 to 150nm.[3] Above a few hundred nm in size, these nanoparticles transform into 2H-MoS2 platelets. Fullerene-like particles have been …
