Functional material, an apparatus for purification of a fluid, an apparatus for a containing a liquid, a pulverized product and method of manufacturing same

A method of manufacturing a pulverized product, the method comprising:

• preparing a porous carbon material including solidifying a plant-derived material to form a solidified porous carbon material, wherein the solidified porous carbon material is a cylindrical shape, a firewood bar shape, a coil shape or a granular shape;
• heating the solidified porous carbon material at a temperature ranging from 400° C. to 1400° C.;
• and
• after heating the solidified porous carbon material, treating the solidified porous carbon material using an acid or an alkali,
• wherein a value of a pore volume of the porous carbon material based on an MP method is in a range of 0.04 cm3 per 1 cm3 to 0.09 cm3 per 1 cm3 of the porous carbon material,
• wherein a value of a cumulative pore volume in a range of 0.05 μm to 5 μm in pore size of the porous carbon material based on a mercury press-in method is in a range of 0.4 cm3 per 1 gram of the porous carbon material to 1.2 cm3 per 1 gram of the porous carbon material;
• processing the porous carbon material to provide a pulverized form of the porous carbon material;
• and
• processing the pulverized form of the porous carbon material to form the pulverized product.
