摘要
Li2ZrO3 particles were prepared by spray pyrolysis and solid state reaction to compare their CO2 absorption capacity and rate. The former method provided much higher CO2 absorption capacity and rate than those by the latter. Spherical particles of rather small and uniform size allow the faster diffusion of Li to the surface for higher CO2 absorption capacity and regeneration of absorption through CO2 recovery.
