A novel high-efficiency (Zr-Ce) incorporated Ca(OH)(2) nanostructure adsorbent for CO2 capture was synthesized using calcium acetate monohydrate precursor containing n-hexadecyltrimethyl ammonium bromide and sodium hydroxide via a precipitation method. The cyclic carbonation/calcination performance of the novel adsorbent was investigated using a thermogravimetry-differential thermal analysis (TG-DTA) apparatus. The novel (Zr-Ce) incorporated Ca(OH)(2) adsorbent exhibited a significantly improved CO2 adsorption capacity, cyclic stability and remarkable carbonation conversion up to similar to 96% for 14 carbonation/calcination cycles compared with the pure Ca(OH)(2) adsorbent. This result may be due to the large Brunauer-Emmett-Teller (BET) surface area (80.23 m(2)/g), the wide range of mesopore size distribution (2-30 nm) and the presence of the high temperature sintering resistance Ce2Zr3O10 compound of the novel adsorbent.
