    • A method of manufacturing a mesoporous carbon structure using spray drying or spray pyrolysis is provided to manufacture porous carbon particles with various pore sizes and porosities by using a template that is pyrolyzed in a carbonization temperature range of a carbon precursor, or removed by the post-treatment process after the carbonization to form pores. A method of manufacturing a porous carbon structure comprises the steps of: (a) mixing a carbon precursor, a pyrolyzable template that is pyrolyzed in a temperature range or less where the carbon precursor is carbonized, and a solvent to prepare a spray solution; and (b) performing a heat treatment process after spray heat-treating or spray drying the spray solution. The method comprises carbonizing a carbon precursor contained in a composite of the carbon precursor with the pyrolyzable template through a heat treatment process, thereby simultaneously crystallizing the carbon precursor and pyrolyzing the template to form a pre structure. A method of manufacturing a porous carbon structure comprises the steps of: (a) mixing a carbon precursor, a hard template, and a solvent to prepare a spray solution; (b) forming a composite of the carbonized carbon structure and the hard template by performing a heat treatment process after spray heat-treating or spray drying the spray solution; and (c) removing the template from the formed composite of the carbon structure and the hard template.
