- Abstract
Electrostatic spray pyrolysis has been used to prepare Li2ZrO3 nanopowder for CO2 sorbent. Final annealing was done at 900 °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 rain with high sorption rate. Absorbed CO2 was mostly generated by heating at 800 °C.
