Title: METHOD FOR PRODUCING ACTIVATED CARBON
Abstract:
Provided is a method for efficiently producing activated carbon having an increased proportion of extremely small-sized micropores 1 nm or less in diameter even among micropores 2 nm or less in diameter. This method for producing activated carbon includes an activation step that activates an activated carbon precursor containing a metal component by carbon dioxide gas as an introduction gas and obtains activated carbon having a ratio (pore volume B/total pore volume A) of the pore volume B 1.0 nm or less in diameter to the total pore volume A of 0.5 or higher, and the metal element that constitutes the metal component is selected from the group consisting of group 2 elements, group 3 elements, group 4 elements, group 5 elements, group 6 elements, group 7 elements, group 9 elements, and rare earth elements.
