摘要：

The adsorption of CO2 on both commercial and prepared porous ceria samples was investigated. The two samples exhibited distinctive variations in morphology and texture. The porous sample, characterized by a sponge-like morphology and high surface area, demonstrated a superior affinity for CO2 compared to the non-porous sample with a plate-like structure. Additionally, at elevated temperatures, the adsorption capacity of both samples decreased; however, the porous ceria sample continued to adsorb more CO2 than the commercial sample. Furthermore, the reusability of the porous ceria sample was examined, revealing a more favorable adsorption behavior compared to the commercial sample, and notably, it exhibited this performance without necessitating any thermal treatment.
