    Abstract: Provided is an electrode catalyst production method capable of obtaining, through an easy operation, an electrode catalyst whose chlorine (Cl) species content has been reliably and sufficiently reduced, even when using as an electrode catalyst raw material an electrode catalyst precursor containing a high concentration of chlorine.The method is to produce an electrode catalyst having a core-shell structure including a support, a core part formed on the support and a shell part formed to cover at least a part of a surface of the core part. The method includes a first step (1) of retaining a liquid containing ultrapure water, a reductant such as a hydrogen-containing gas and an electrode catalyst precursor under at least one stage of a predetermined temperature for a predetermined retention time, such electrode catalyst precursor being produced using a material containing chlorine (Cl) species, and exhibiting a chlorine (Cl) species concentration not lower than a predetermined first chlorine (Cl) species concentration when measured by X-ray fluorescence (XRF) spectroscopy.

    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.
