Catalytic Chemical Vapor
Deposition (CCVD) or
simply Chemical Vapor
Deposition (CVD) with
variants like thermal
and plasma-assisted is
the dominant commercial
technique for the
fabrication of VGCF and
VGCNF. Here, gas-phase
molecules are decomposed
at high temperatures and
carbon is deposited in
the presence of a
transition metal
catalyst on a substrate
where subsequent growth
of the fiber around the
catalyst particles is
realized. In general,
this process involves
separate stages such as
gas decomposition,
carbon deposition, fiber
growth, fiber
thickening,
graphitization, and
purification and results
in hollow fibers. The
nanofiber diameter
depends on the catalyst
size. The CVD process
for the fabrication of
VGCF generally falls
into two categories: 1)
fixed-catalyst process
(batch), and 2)
floating-catalyst
process (continuous).
