SPHERICAL POROUS CARBON STRUCTURE AND PRODUCING METHOD OF THE SAME

摘要

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.
