The present invention relates to a method for producing activated carbon from tobacco leaves by simultaneous carbonization and self-activation in an inert gas environment. Activated carbon produced by this novel process, 600~2000m 2 g -1, preferably have a specific surface area of 1700 m 2 g -1, it has a wide range of amounts of ultra micropores and mesopores, micro pore volume to The mesopore volume ratio is a minimum of 3: 1, a maximum of 10: 1, preferably 4: 1. The average pore diameter (L 0 ) is in the range of 0.55 to 1.3 nm, preferably 0.8 to 1.2 nm, and the total pore volume is 0.2 to 1.25 cm 3 g −1 . . The present invention also refers to an electrode comprising activated carbon having the above properties and an electrochemical capacitor comprising such an electrode. [Selection] Figure 1 |
