Provided is an adsorbent for capturing carbon dioxide and a method for manufacturing same, and more particularly, to an adsorbent for capturing carbon dioxide, including a magnesium oxide/titanium dioxide composite having wide surface area, large pore volume and good COadsorption performance, and a method for manufacturing same. According to the present invention, a novel MgO based composite metal oxide which may stably adsorb COat a low temperature such as room temperature is provided. The adsorbent for capturing carbon dioxide, including a magnesium oxide/titanium dioxide composite has good thermal stability, and controls basic sites easily, and is used in various fields for capturing carbon dioxide. In addition, by controlling the molar ratio of the metal ions of the magnesium oxide/titanium dioxide composite and controlling morphology, an adsorbent for capturing carbon dioxide having large surface area and pore volume and strong basic sites may be provided.

Adsorbent for capturing carbon dioxide comprising magnesium oxide/titanium dioxide composite and method for manufacturing same

Disclosed herein are a novel crown ether with bulky and rigid groups and a method for preparing the same. Also provided are a lithium adsorbent comprising the novel crown ether immobilized onto a nanofiber, and a method for preparing the same. The lithium-selective crown ether is synthesized through intermolecular cyclization between a bulky epoxide and a rigid aromatic compound such as 1,2-dihydroxybenzene, and can effectively recover lithium ions. For use as a lithium adsorbent, the novel crown ether with both bulky and rigid subunits is immobilized onto a polymer nanofiber. The crown ether-immobilized polymer nanofibers may be formed into a recyclable membrane.

Disclosed are a composite nanofiber membrane for the adsorption of lithium, a method for preparing the same, and a lithium recovery apparatus and method using the same. The composite nanofiber membrane for the adsorption of lithium is immobilized with manganese oxide selectively adsorptive of lithium. The composite nanofiber membrane for lithium adsorption exhibits high selectivity for lithium ions and allows for the rapid and easy diffusion of lithium ions through interstitial spaces of the adsorbent. Particularly, the lithium recovery apparatus using the composite nanofiber membrane for lithium adsorption is able to effectively adsorb lithium ions dissolved in seawater in a selective manner within a short period of time, thus reducing the time taken for the adsorption process.
