Carrier for dry adsorbent for carbon dioxide including spherical silica whose surface is engraved in the form of nanowires and method for preparing the same

Abstract

Provided are a carrier for a dry adsorbent for carbon dioxide, including spherical silica whose surface is engraved in the form of nanowires, and a method for preparing the same. Although the carrier for a dry adsorbent for carbon dioxide including spherical silica that has nanowires on the surface thereof has a very non-uniform shape, it serves better as a host structure adsorbing carbon dioxide as compared to the conventional carrier for a carbon dioxide adsorbent, and thus may be used for a host-guest adsorbent applicable to a fluidized bed process. In addition, the method for preparing a carrier for a carbon dioxide adsorbent provides nanowire-coated silicon spheres having an increased surface roughness and an increased surface area, thereby providing increased carbon dioxide capturing efficiency. Further, since the method for forming nanowires is simple, it is easy to carry out mass production without any separate process, thereby providing excellent cost efficiency.
