Abstract
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(CO3)2 particles or particles in which MgCO3 or Mg(OH)2 are attached to the outside of BaMg(CO3)2; 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.
