Plasma synthesis of carbon nanowalls and their applications

Carbon nanowalls have three-dimensional nanostructures made by the self-organization of two-dimensional carbon, where several to dozens of layers of multi-layer graphene grow almost perpendicularly on various substrates. There are reports of the synthesis on the substrate heated to about 600-700 deg C using various plasma CVD methods. Carbon nanowalls are characterized by their wide specific surface area and excellent conductivity, and are expected to be applied as batteries, capacitors, electrodes for biosensors or electrochemical sensors, etc. in combination with surface modification with metal nanoparticles or biomolecules.
