Reductive destruction of halogenated hydrocarbons in liquids and solids with solvated electrons

Cosmic-ray-driven electron-induced reactions of halogenated molecules adsorbed on ice surfaces: Implications for atmospheric ozone depletion and global climate change

“…And the solvation of electrons generated by adding electron donors (alkali metals) into polar media such as liquid ammonia had been adopted as an effective method for dehalogenation of environmentally hazardous halogenated materials including CFCs. In the latter, halogen atoms were reduced to halogen ions and dechlorination of CFCs was also observed to be much more efficient than defluorination [84,85]. Realizing these observations, Lu and Madey [11,12,79,80] …”

“…Finally, the DET mechanism addressed in this study may have fundamental and practical significance in many multidisciplinary areas, no limit to the applications in biotechnology, e.g., for the analysis of human milk triacylglycerols [81] human blood [82] and proteins [140], in disposal of environmentally hazardous halogenated materials [84,85], and in the activation of anticancer drugs [21][22][23] and the fundamental understandings of molecular pathways leading to DNA damage and cell death relevant to aging, stroke and cancer and their treatments [24]. For instance, it was recently found by Lu [23] that the DET reaction of cisplatin-the most widely used drug for cancer treatment-with prehydrated electrons generated in a biological environment can greatly enhance the therapeutic efficacy of cisplatin in combination with ionizing radiation.…”

Electron-driven chemistry of halogenated compounds in condensed phases: Effects of solvent matrices on reaction dynamics and kinetics

“…In the gas-phase, examples of EDPs include plasma and high-energy remediation of environmental pollutants [6,13], as well as reactions that occur in atmospheric [14] and interstellar chemistry [15]. EDPs in condensedphase environments include nanolithography [16] and radiation processing of toxic chemicals [17]. Indeed, the diversity of media where EDPs are prevalent accounts for the study of electron-stimulated processes in experiments that range from molecular beam scattering to surface photochemistry.…”

Negative-Ion Enhancements in Electron-Stimulated Desorption ofCF2Cl2Coadsorbed with Nonpolar and Polar Gases on Ru(0001)

“…(1c)] in the gas phase [2,3]. In fact, the generation of solvated electron by dissolving alkali-metal atoms in liquid solvents has been applied to dehalogenation of environmentally hazardous halogenated organic compounds, in which halogen atoms are reduced to halogen ions [21,22] and dechlorination can be much more efficient than defluorination. This qualitatively agrees with the present observation that the magnitude of enhancement of Cl 2 is much larger than that of F 2 for H 2 O or NH 3 coadsorption.…”
