The results indicate that the loading capacity of Li2ZrO3 for CO2 is slightly improved than that reported previously. The absorption capacity attain to about 25(±0.6)%(wt)at 500℃kept 3h in an atmosphere containing 20%CO2 (balanced by air). Moreover, the temperature of synthesis is lower than the temperature reported in the literature, and also the time of synthesis is shorter.展开更多
