N2 - Lithium cuprate (Li2CuO2) was obtained by a solid state reaction and a subsequent ball milling process; then, the samples were characterized structurally and microstructurally. Additionally, both the Li2CuO2 ball milled and the solid state samples, for comparison purposes, were tested in the CO2 chemisorption process at moderate and low temperatures under different reaction conditions: (i) at moderate CO2 pressure and (ii) in the presence of water vapor. In both cases, the textural and microstructural properties of the ball milled Li2CuO2 samples showed excellent CO2 chemisorption properties which are significantly enhanced due to CO2 pressure effects or the presence of water vapor. All these results were attributed to the textural and morphological changes evidenced in the samples. The observed surface area increments show preponderant effects during CO2 chemisorption at low and moderate temperatures.
