<p>A carbon grid shaped nanopore production method comprises: a process wherein a precursor is prepared as a starting material; a stabilization process wherein the precursor is oxidised by being brought into contact with air; a carbonization process wherein the carbon form formed in the stabilization process is carbonized under oxygen-free conditions so as to form primary pores; a surface treatment process wherein the carbon form in which the primary pores have been formed is subjected to a surface treatment by being brought into contact with ozone; a dipping process wherein the carbon form which has been subjected to the surface treatment is dipped in an aqueous solution of an alkali metal; and a surface modification process wherein surface modification is carried out by inducing oxidation and reduction of the alkali metal while raising the temperature to no more than 800°C in an oxygen-free atmosphere. Also, the production method comprises a process in which, after the surface modification has been completed, cooling is carried out to room temperature under oxygen-free conditions and then dipping is effected for at least 1 hour in a sulfuric acid solution of no more than 5M, and cleaning is carried out in distilled water and then drying is carried out at about 150°C in the air.</p> |
