Abstract

•Simultaneous titration-calcination way to prepare core–shell (CaCO3/Ce(OH)CO3)@Ce(OH)CO3.•Novel core–shell (CaO/CeO2)@CeO2 with strong stability of CO2 adsorption.•CO2 adsorption amount still maintained at about 430 mg/g after 15 cycles.•CeO2 uniformly dispersed in CaO pore channels for stable pore and anti-sintering performance.•The authors declare no competing financial interests.
