Resumen:

Li2CuO2 was synthesized using a solid-state reaction, and then different water sorption experiments were performed using N2 and CO2 as carrier gases. When the N2-H2O flow gas was used, Li2CuO2 showed a water vapor sorption because of two different processes: superficial hydration and hydroxylation. However, if CO2 was used as the water vapor carrier gas, the Li2CuO2 carbonation process was observed at low temperatures (30-80 °C), the carbonation process was induced by the lithium ceramic superficial hydroxylation. The Li2CuO2captured 6.7 mmol of CO2 per gram of ceramic (efficiency of 73%), a considerably high CO2amount among different materials. © 2015 The Authors.
