Reactivity of presolvated and solvated electrons with CO 2 in water up to 118 bar at 298 and 308 K
Résumé
The reactivity of electrons in the CO2-water system was evaluated through picosecond electron pulse radiolysis at different gas pressures (ranging from 1 to 118 bar) and temperatures (25 and 35 °C) coupled with UV-vis transient spectroscopy. A custom-made spectroscopic cell was utilized for these experiments, which allowed for regulation of temperature and pressure. The scavenging of electrons was measured directly at gas pressures even in the supercritical state, and the results showed a non-monotonic dependence of electron reactivity with CO2 concentration, in agreement with the changing molar concentration of CO2 in water under varying pressure.
