DETAILED DESCRIPTION - The production method of three-dimensional nanoporous graphene involves: (1) preparation of copper-manganese alloy foil sheet by taking 20-40 atomic% copper and 60-80 atomic% manganese; (2) alloying copper-manganese alloy foil sheet obtained in step (1), and preparing nanoporous copper foil having layered nanoporous structure as function of alloying time and changing concentration of corrosion liquid; and (3) placing nanoporous copper foil obtained in step (2) in quartz boat, then placing quartz boat in middle constant temperature zone of reaction tube under argon atmosphere, heating at 200-400 degrees C under hydrogen atmosphere when the temperature is increased to designated temperature with acetylene growth of hydrogenated graphite, where the ratio of acetylene, argon and hydrogen is 1-50:200-500:50-200, closing acetylene and argon after 60 minutes, quickly removing quartz boat from middle constant temperature zone of reaction tube to outside of furnace, increasing furnace temperature to 500-1100 degrees C under hydrogen atmosphere having hydrogen gas rate of 50-200 sccm, increasing furnace temperature to specified temperature of quartz boat, then quickly moving to middle constant temperature zone of reaction tube, calcining at room temperature for 0.5-30 minutes, quickly removing quartz boat from middle constant temperature zone of reaction tube to the outside of furnace after the completion of calcination, opening the lid of furnace, taking samples at room temperature under hydrogen atmosphere, then immersing samples in corrosion liquid to remove nanoporous copper, etching for 2-12 hours and cleaning to obtain self-supported three-dimensional nanoporous graphene thin film.
