Abstract:
An adsorbent for carbon dioxide may include a structure that includes composite metal oxide including a first metal (M1) and a second metal (M2) linked through oxygen (O). The first metal (M1) may be selected from an alkali metal, an alkaline-earth metal, and a combination thereof. The second metal (M2) may have a trivalent oxidation number or greater. The composite metal oxide may include mesopores inside or in the surface thereof. The adsorbent may be included in a capture module for carbon dioxide. A method of reducing emissions may include adsorbing carbon dioxide using the adsorbent for carbon dioxide.
Abstract:
An adsorbent for carbon dioxide may include an inorganic oxide porous structure having a plurality of mesopores and an active compound bound to the surface of the mesopores. The active compound may be selected from an alkali metal-containing compound, an alkaline-earth metal-containing compound, and a combination thereof. Various example embodiments also relate to a method of preparing the adsorbent for carbon dioxide and a capture module for carbon dioxide including the adsorbent for carbon dioxide.
Abstract:
An adsorbent for carbon dioxide may include a mesoporous inorganic oxide having a crystalline halide of an alkali metal or alkaline earth metal supported thereto and a chemical species containing phosphorous (P), sulfur(S), or boron (B) supported thereto.
