Selective synthesis of marimo carbon using Fluidized-Bed chemical vapor deposition

Marimo carbon is a fibrous carbon material that has attracted attention in many fields, such as for its use in electronic devices and capacitors. It has diamond particles in its core, with carbon nanofilaments radiating outward from diamond core. In this study, we synthesized marimo carbon using an oxidized diamond-supported catalyst by fluidized bed chemical vapor deposition (CVD) and rotary fluidized bed CVD. This demonstrated that fluidized bed technology can be used for the cost-efficient, large-scale production of uniform marimo carbon.
