NOVELTY - Manufacture of graphene nanowall involves placing a quartz boat containing foamed nickel and ferrocene in a heating zone at inflow end of purging of reaction gas, placing a quartz boat cleaned with stainless steel sheet or wire mesh at heating zone close to reaction gas outflow end, heating to 1000-1200 degrees C under inert gas atmosphere, purging gas comprising hydrogen and carbon source gas in volume ratio of 1:6-2:3, reacting for 1 minute to 3 hours, and cooling to room temperature using inert gas comprising argon or nitrogen. USE - Manufacture of graphene nanowall. ADVANTAGE - The method enables simple and economical large-scale manufacture of thin-transparent graphene nanowall having large surface area and reduced surface defects. DETAILED DESCRIPTION - Manufacture of graphene nanowall involves placing a quartz boat containing foamed nickel and ferrocene in a heating zone at inflow end of purging of reaction gas, placing a quartz boat cleaned with stainless steel sheet or wire mesh at heating zone close to reaction gas outflow end, heating to 1000-1200 degrees C under inert gas atmosphere, purging gas comprising hydrogen and carbon source gas in volume ratio of 1:6-2:3, reacting for 1 minute to 3 hours, and cooling to room temperature using inert gas comprising argon or nitrogen at flow rate of 10-40 sccm. The carbon source gas is hydrocarbon. The flow rate of carbon source gas is 80-180 sccm.
