The low-energy electron-induced chemistry of condensed CCl₄ has been investigated with use of post-irradiation temperature-programmed desorption. These experiments were partly motivated by the growing interest in developing facile and economical methods for decomposing CCl₄ and other halocarbons which through widespread use in industry have become potent environmental pollutants. The experimental procedure involves low-energy (50 eV) electron irradiation (fluence ≤2 × 10¹⁶ electrons cm^-2) of nanoscale thin films (5 monolayers) of CCl₄ grown at 100 K on a Mo(110) single crystal under ultrahigh vacuum (UHV) conditions. Results of post-irradiation temperature-programmed desorption experiments were used to identify C₂Cl₄, C₂Cl₆, C₃Cl₆, C₄Cl₆, and C₅Cl_x as low-energy electron-induced reaction products of condensed CCl₄.
