The HCNF isˆbrilliform carbon materials with spiral and twisted shapes. The HCNF is divided into the groups of carbon nanocoil (CNC) and nanotwist (CNTw). They are synthesized by means of catalytic chemical vapor

The CNH is a particulate-form material and is produced by the evaporation of graphite with a laser or an arc discharge. The one of possible applications is the catalyst-supported electrode for fuel cell. The CNB is synthesized from an arc soot (or called arc black) and also from a particular-type acetylene black by means of high-temperature treatment under inert gas. Its potential applications are mentioned.
