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 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 m2
/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
