CO2-Activation by size-selected tantalum cluster cations (Ta1–16+): thermalization governing reaction selectivity

Autor: Nikita Levin, Johannes T. Margraf, Jozef Lengyel, Karsten Reuter, Martin Tschurl, Ulrich Heiz

Publikováno v: Physical Chemistry Chemical Physics. 24:2623-2629

Tantalum cluster cations react with CO2 either via transfer of oxygen atoms to the clusters or the adsorption of an entire molecule. The released energy and vibrational heat capacities are assigned to determine the branching ratios of the pathways.
