Abstract: The present invention relates to a method of producing a porous composite comprising single-atom metal catalysts and nitrogen atoms by using a hierarchical carbon material from a carbon dioxide-containing gas. According to the present invention, a composite material is produced by producing a porous carbon material using nanosized templates and carbon dioxide, producing carbon nanotubes from the composite material through a self-templating process, and adding single-atom catalysts to the carbon nanofibers. In addition, it is possible to produce a composite having significantly improved porous characteristics and electrochemical properties by nitrogen atom doping using a nitrogen precursor. The produced composite may be easily applied to a high-energy storage device such as a lithium-sulfur battery.

Abstract: The present invention relates to: oxygen carrier particles having a metal oxide-perovskite core-shell structure; and a chemical-looping thermochemical water/carbon dioxide splitting process using the same. By using the oxygen carrier particles having a metal oxide-perovskite core-shell structure in the chemical-looping thermochemical water/carbon dioxide splitting process, it is possible to produce hydrogen/carbon monoxide from water/carbon dioxide in high yield by efficiently overcoming the disadvantages of conventionally used oxygen carrier particles.
