Abstract

A spherical-like mesoporous cerium oxide (CeO2-BT) was prepared through biotemplating method using egg-shell membrane (ESM) as a template. The CeO2-BT has shown a smaller nanoparticle size (30–34 nm) and larger surface area (26.52 m2/g) compared to CeO2 prepared through thermal decomposition method (CeO2-TD). The CeO2-BT has also shown a lattice expansion with the high defect site and oxygen vacancies as evidenced by the Williamson-Hall (W-H) plot. These enhancements have resulted in excellent CO2 uptake of CeO2-BT (1.412 mmol/g), being 12-fold higher than that of CeO2-TD at 1 bar and 25 °C.
