Chemistry of Solvated Electrons in Molten Alkali Chloride Salts

We use ab initio molecular dynamics to study the electronic structure and the chemistry of the solvated electrons created when alkali atoms are dissolved in alkali chloride molten salt. We find that solvated electrons pair up to form a two-electron species. This species is a very strong reductant which reduces Ag+ to Ag- or Ag(s), dissociates H-2 to form 2H(-), dissociates CH4 to form CH3- and H-, and converts N-2 to N-2(2-). We also study how these properties depend on the composition of the alkali chloride salt.
