A Critical Assessment of the Synthesis of Diameter and Chirality Controlled CNTs in Zeolites
We here present the controlled synthesis of ultra-small diameter nanotubes in well-defined subnanometer sized confined space within zeolites.

Zusammenfassung: | We here present the controlled synthesis of ultra-small diameter nanotubes in well-defined subnanometer sized confined space within zeolites. A critical view on the zeolite occluded nanotube growth is presented. Thermogravimetric analysis and optical techniques are evaluated for nanotube characterization. The introduction of Bro̸nsted acid sites in the zeolite framework leads to optimized yields. As temperatures below 500{degree sign}C are envisioned for nanotube synthesis, zeolite occluded nanotubes are compatible with current CMOS technology platform, in densities in accordance with ITRS standards for future interconnects, making zeolites a viable pathway for integration of SWCNTs in the chip of the future. |
