Carbon nanowalls are carbon nanostructures consisting of arrays of graphitic carbon plates which are mainly positioned
perpendicularly to the growth surface. Carbon nanowalls have received considerable interest in recent years, since they are closely
related to graphene from the structural point of view, while maintaining an open honeycomb lattice on the nanoscale. They are
thus believed to be an interesting electrode material for many applications since they offer high chemical resistance, low electrical
resistance and high surface area. In this paper we are presenting a method that allows the growth of thick layers of carbon nanowalls
onto flat and porous substrates, both carbon and refractory metal based. Such methods are promising for making electrodes for use
in electrochemical devices.
