CO2 adsorption - solid materials
Equilibrium of SrO/SrCO3 and stability
SrO requires temperatures higher than 1000 °C to capture CO2. As shown below, for a CO2 source containing 20% CO2, higher than 1050 °C was

Influence of Na addition and CO2 concentration
Different ratios of Li and Na were investigated for the development LiNaZr adsorbents, which were prepared through simple impregnation (https://doi.org/10.1016/j.jece.2019.102927). The addition of Na showed

Influence of water content in CO2 sources
As shown below, in general the presence of water facilitated the capture of CO2 using Na and K promoted LiZr adsorbents (https://doi.org/10.1016/j.jallcom.2021.162419). In particular, when
