8 Claims

1. A method of producing a porous carbon, comprising:

a first step of carbonizing a material containing a carbon source and a template source, to prepare a carbonized product; and a second step of immersing the carbonized product into a template removing solution, to remove a template from the carbonized product, the method characterized by:

controlling type, amount, or ratio of functional groups that are present in the porous carbon by changing at least two or more of the following conditions: type of the material, ratio of the carbon source to the template source, size of the template, and type of the template removal solution.
