Spherical, porous carbon structure and a production method therefor

摘要

The present application relates to a spherical, porous structure which is formed using a mold taking the form of a spherical nanoparticle aggregate, and relates to a production method therefor. According to one aspect of the present application, the production method for the spherical, porous structure comprises: the use of a mold taking the form of a spherical nanoparticle-carbon precursor aggregate comprising a carbon precursor on the surfaces of a plurality of nanoparticles, formed by removing solvent from droplets comprising the carbon precursor and the plurality of nanoparticles.

1. A production method of a spherical porous carbon structure via a sacrificial template process, the production method comprising:
using a spherical nanoparticle-carbon precursor coaggregate as a template, wherein the spherical nanoparticle-carbon precursor coaggregate is formed by:
removing a solvent from a droplet including plural nanoparticles and a carbon precursor, the spherical nanoparticle-carbon precursor coaggregate including the carbon precursor on a surface of the plural nanoparticles, andremoving the solvent to form a spherical nanoparticle coaggregate by self assembly from the plural nanoparticles included in an oil-in-water type droplet or a water-in-oil type droplet.
