Electrostatic spray pyrolysis has been used to prepare Li2ZrO3 nanopowder for CO2 sorbent. Final annealing was done at 900 st.C for 30 min in air. The CO2 sorption/desorption ability of the annealed powder has been investigated by thermogravimetric analysis and Fourier transform infrared spectroscopy. When Li2ZrO3 nanopowder was exposed to CO2 environment at 500 ?C, the theoretical absorption weight was gained within 250 min with high sorption rate. Absorbed CO2 was mostly generated by heating at 800 st.C.
