Disclosed is a metal complex including: a tin oxide; titanium oxide nanorods in a rutile phase formed on the tin oxide; and titanium oxide nanoparticles in an anatase phase formed on the titanium oxide nanorods in a rutile phase, and a preparation method thereof, and can be used as a catalyst support in various forms.

Metal complex of fluorinated tin oxide and titanium oxide and preparation method thereof

Provided is a preparation method of an oxygen-selective adsorbent selectively adsorbing oxygen in the air and an oxygen-selective adsorbent prepared thereby. The preparation method includes: preparing BaMg(CO)particles or particles in which MgCOor Mg(OH)are attached to the outside of BaMg(CO); and sintering the particles at a high temperature. The oxygen-selective adsorbent according to the present invention may adsorb oxygen in the air at a fast rate as compared with an existing oxygen-selective adsorbent and have high thermal stability and excellent oxygen adsorptivity.

Oxygen-selective adsorbent having fast adsorption rate and preparation method thereof

An apparatus for separating carbon dioxide is provided. The apparatus includes: an absorption column in which carbon dioxide in off-gas is allowed to react with an absorbent solution so as to strip the carbon dioxide from the off-gas; a regeneration column in which the carbon dioxide is removed from the absorbent solution to regenerate the absorbent solution; and an ion-exchange column including a chamber having a cathode chamber space that receives the absorbent solution from the absorption column and an anode chamber space that receives the absorbent solution from the regeneration column, the ion-exchange column further including a permeable membrane that divides the chamber into the cathode chamber space and the anode chamber space.
