CONSTITUTION: A colloidal crystal layer is formed on a conductive transparent substrate(S100). A porous first transition metal oxide layer is formed by selectively removing the colloidal crystal layer(S200). A second transition metal oxide layer is formed on the porous surface of the first transition metal oxide layer by post-processing the porous first transition metal oxide layer with a second transition metal oxide containg-precursor solutions(S300). A photosensitive dye is absorbed in the first transition metal oxide layer with the second transition metal oxide layer on the porous surface thereof(S400).

PURPOSE: A spherical porous carbon structure and a method for manufacturing the same are provided to apply micrometer sizes to the spherical porous carbon structure by using spherical nanoparticle-carbon precursor aggregate as a template. CONSTITUTION: Spherical nanoparticle-carbon precursor aggregate(100) is used as a template. In the spherical nanoparticle-carbon precursor aggregate, a carbon precursor(30) is arranged on the surface of a plurality of nanoparticles(10). The spherical nanoparticle-carbon precursor aggregate is formed by eliminating a solvent(20) from droplets(40) containing the carbon particles and carbon precursor. A method for manufacturing a spherical porous carbon structure includes the following: the spherical nanoparticle-carbon precursor aggregate is calcinated under a reducing atmosphere to form spherical nanoparticle-carbon aggregate; and a plurality of nanoparticles is eliminated from the spherical nanoparticle-carbon aggregate.
