Graphene based materials, for example, carbon nanotube and graphene sheet itself have a wide scope of potential applications. Among this grapheme based materials, carbon nano walls (CNWs) are self-upheld organization of few-layer graphenes standing vertically on the substrate to shape 3- dimensional structure. The mazelike design of CNWs with huge surface region graphene planes would be valuable as anodes for vitality stockpiling gadgets, electrochemical and biosensors and framework for cell refined. CNWs and related materials can be blended by a few plasma upgraded concoction fume testimony (PECVD) strategies on warmed substrates utilizing CH4 and H2 blends. Control of CNW structures including dividing between adjoining nano walls and crystallinity is noteworthy for the common sense applications. Besides, surface functionalization including surface end and design with synergist metal nanoparticles ought to be set up. We report the current status of manufacture and structure control of CNWs utilizing a few PECVD methods. Additionally, CNW surface was enlivened with Pt nanoparticles by the decrease of chloroplatinic corrosive or by the metal-natural concoction affidavit utilizing supercritical liquid. We likewise report the exhibitions of hydrogen peroxide (H2O2) sensor and energy component, where CNW terminal was utilized. For the H2O2 detecting application, CNWs were developed on carbon fiber paper (CFP) utilizing PECVD with CH4/Ar blend to build the surface zone. At that point, CNW surface was enlivened with Pt nanoparticles by the decrease of H2PtCl6 in arrangement.
