In this paper, we report the development of synthetic
CaO
-based sorbents via a fast precipitation method with the assistance of sodium poly(styrenesulfonate) (
PSS
). The effect of
PSS
on physical properties of the
CaO
sorbents and their CO2 capture performance were investigated. The presence of
PSS
dispersed the
CaO
particles effectively as well as increased their specific surface area and pore volume remarkably. The obtained porous spherical structure facilitated CO2 to diffuse and react with inner
CaO
effectively, resulting in a significant improvement in initial CO2 carbonation capacity. A proper amount of Mg(2+) precursor solution was doped during a fast precipitation process to gain
CaO
-based sorbents with a high anti-sintering property, which maintained the porous spherical structure with the high specific surface area.
CaO
-based sorbents derived from a MgxCa1-xCO3 precursor existed in the form of
CaO
and MgO. The homogeneous distribution of MgO in the
CaO
-based sorbents effectively prevented the
CaO
crystallite from growing and sintering, further resulting in the favorable long-term durability with carbonation capacity of about 52.0% after 30 carbonation/calcination cycles.
