A method for producing an amorphous activated carbon material includes heating a carbon precursor to a temperature effective to form a partially-dense amorphous carbon, and activating the partially-dense amorphous carbon to produce an amorphous activated carbon. To facilitate efficient activation of the amorphous carbon, the carbonization is controlled to produce an amorphous carbon material that, prior to activation, has a density of from 85% to 99% of a maximum density for the amorphous carbon.

There is provided a method for producing an aluminum structural body, including an electrical conduction treatment of forming an electrically conductive layer made of aluminum on a surface of a resin molded body and a plating process of plating the resin molded body subjected to the electrical conduction treatment with aluminum in a molten salt bath. Even with a porous resin molded body having a three-dimensional network structure, the method allows the surface of the porous resin molded body to be plated with aluminum, thus forming a high-purity aluminum structural body having a uniform thick film. Porous aluminum having a large area is also provided.
