We find that the dominant channel is the production of CD 4 +, followed by DOCO + and CD 3 +, as a minor endothermic channel. Concerning the product branching ratios ( CD 4 +/ CD 3 +/DOCO +) there is substantial disagreement among the values reported in the literature. We find that the reactivity depends on the reagent collision energy, but not so much on the vibrational excitation of CO 2 +. The experiments were performed by a guided ion beam apparatus coupled to synchrotron radiation in the VUV energy range to produce vibrationally excited ions. In this paper, we investigate the reaction of CO 2 + with methane by changing either the kinetic energy of CO 2 + or its vibrational excitation. However, putting the same amount of energy in a different form may affect the reactivity differently. Energy, in the form of kinetic or internal excitation of reagents, influences chemical reactions.
#ORGANIC CHEMISTRY REACTIVITY OF CARBON DIOXIDE SERIES#
Non-equilibrium plasmas are currently explored for their capability to activate very stable molecules (such as methane and carbon dioxide) and initiate a series of reactions involving highly reactive species (e.g., radicals and ions) eventually leading to the desired products. The reactivity of CO 2 + with CD 4 has been experimentally investigated for its relevance in the chemistry of plasmas used for the conversion of CO 2 in carbon-neutral fuels.
