Synthesis of single-walled carbon nanotubes by laser ablation of organometallic precursors in air atmosphere

Resumen del trabajo presentado a la International Conference on Carbon Nanoscience and Nanotechnology (NanoteC), celebrada en Zaragoza (España) del 27 al 30 de agosto de 2019.Single-walled carbon nanotubes (SWCNTs) possess exceptional mechanical and electrical properties, which enables their use in high-tech applications such as fabrication of reinforced polymers or their use as conductive phase in novel lithium-ion batteries. The most common methods to synthesize SWCNTs, which include chemical vapour deposition, are discharge or laser ablation, usually reqmre of the use of vacuum or an inert atmosphere. In this work, we present a one-step, simple method to produce SWCNTs by a continuous-wave laser ablation of an organometallic compound under air atmosphere. The nanotubes are present in the form of small bundles as a minor component of the produced soots and show a narrow diameter dtstnbutron. The effect of the metal and the chemical composition of the ablated ligands into the formation of the SWCNTs will be here discussed
