This paper presents a study on CO₂ atmospheric transformation which was reacted directly with lithium hydroxide solution and metallic lithium. This solution was obtained through the reaction between metallic lithium and deionized water where hydrogen is produced and by exposing the metal at ambient conditions. In the transformation process, atmospheric CO₂ gas reacts directly with LiOH solution, in both cases, the CO₂ transformation kinetics was different. For this purpose, reactions between CO₂ and LiOH solution were carried out under controlled temperature and the second process only with metallic lithium, which was exposed at room temperature, however, in these two processes lithium carbonate oxide was formed and identified. According to the results, the efficiency in CO₂ transformation is a function of temperature value which was variable until completely obtaining the by-product, its XRD characterization indicated the formation only of Li₂CO₃ in both procedures. Under laboratory conditions lithium compounds selectively reacted with CO₂. In the same way, there is an alternative procedure to obtain LiOH and Li₂CO₃ for different applications in various areas.
