3-dimensional(3D)graphenenetworkwithlargesurface
area could be promising material as a platform for
electrochemical and bio applications. This kind of carbon
nanostructure is called as carbon nanowalls (CNWs),
carbon nanoflakes, carbon nanosheets, graphene
nanosheets, and graphene nanowalls. CNWs and
similar materials are basically self-supported network
of few-layer graphenes standing almost vertically on the
substrate to form3D structure. CNWs can be synthesized
by plasma-enhanced chemical vapor deposition (PECVD)
on heated substrates (600-800˚C) employing methane
and hydrogen mixtures. The height of CNWs increases
almost linearlywith the growth period, while the thickness
of each sheet and interspaces between adjacent sheets
are almost constant. The maze-like architecture of
CNWs with large-surface-area graphene planes would
be useful as electrodes for energy storage devices and
scaffold for cell culturing. Especially, combined with
surface functionalization including surface termination
and decoration with nanoparticles and biomolecules,
CNWs can be suitable as platform in electrochemical
and biosensing applications. We have carried out CNW
growth using several PECVD techniques. Moreover,
graphene surface was decorated with Pt nanoparticles
by the reduction of chloroplatinic acid. We also report
the performances of hydrogen peroxide sensor and fuel
cell, where CNW electrode was used. Electrochemical
experiments demonstrate that CNWs offer great promise
for providing a new class of nanostructured electrodes
for electrochemical sensing, biosensing and energy
conversion applications.
