Methane Production from H2 + CO2 Reaction: An Open Molecular Science Case for Computational and Experimental Studies
The article illustrates the synergy between theoretical/computational advances and advanced experimental achievements to pursue green chemistry and circular economy technological implementations. The specific green chemistry focus concerns the production of carbon neutral fuels by converting waste carbon dioxide into methane. Both theoretical-computational and technological means were adopted to design a functional option implementing a heterogeneous catalysis process (Paul Sabatier (PS) catalytic reduction) to convert carbon dioxide into methane, and to further drive its evolution towards the employment of an alternative homogeneous gas phase plasma assisted technology. The details of both the theoretical and the experimental components of the study are presented and discussed. Future potential developments, including industrial ones, are outlined that are also from innovative collaborative economic prosumer model perspectives
Basic features of Ne*–HX (X = Cl, Br) chemi-ionization reactions
Total and partial ionization cross sections for Ne*(3P2,0)–HX (X ¼ Cl, Br) are presented in a comparative way
as a function of the collision energy between 0.02–0.5 eV. New mass spectrometric data on Ne*–HBr
chemi-ionization are discussed and analyzed with already published data on Ne*–HCl, highlighting
similarities and differences of the collisional stereodynamics of the two systems. Basic features of the
interaction potentials, driving reactive collisions, suggest that reaction channels, leading to the formation
of parent HX+ ions in the ground and excited electronic state and to the formation of associated NeHX+
ions as well as of NeH+ proton transfer species, are selectively opened within angular cones exhibiting
different orientation and acceptance
