WebDouble-walled carbon nanotubes (DWCNTs) were synthesized and continuously collected using a water-assisted floating catalyst chemical vapor deposition (FCCVD) method. Differing from the conventional water-assisted synthesis in which water vapor is one part of the carrier gas mixture, we included de-ionized water in the catalyst system, which … WebNov 17, 2024 · The most productive and cost-effective method is the catalytic chemical vapor deposition of nanotubes (CVD) [1,2]. The CVD method is based on the catalytic decomposition of carbon precursors and allows the synthesis of CNTs both on a substrate supported catalyst [3,4], and on a floating catalyst [5,6,7,8] aka aerosol synthesis. The …
