The influence from particle size of carbonized material, pretreatment process, activation method (CO2 physical method, KOH chemical method), activation temperature, activation time on pore structure were studied. The developed amid hole structure activated carbon based coconut shell with specific surface area of 2074 m2/g was prepared at pretreatment temperature of 400˚C, the ratio of alkali and carbon of 2:1, activation temperature of 850˚C, activation time of 1 h.
