▎ 摘　　要

NOVELTY - Manufacturing porous activated carbon comprises (i) uniformly mixing a first organometallic compound precursor containing a first metal and a heating element material; and (ii) heating the mixture using microwaves, where heating element material absorbs microwave to generate heat during the step (ii), and organic component of the first organometallic compound precursor is changed to activated carbon. USE - The hierarchically porous activated carbon is useful for supercapacitor electrode (claimed). ADVANTAGE - The method provides rapid and large amount of porous activated carbon by simultaneously performing carbonization and activation in a single microwave heating process, produces porous activated carbon quickly with high specific surface area.
