- Abstract
Gas phase reactions between PtH n− cluster anions and CO2 were investigated by mass spectrometry, anion photoelectron spectroscopy, and computations. Two major products, PtCO2H− and PtCO2H3−, were observed. The atomic connectivity in PtCO2H− can be depicted as HPtCO2−, where the platinum atom is bonded to a bent CO2 moiety on one side and a hydrogen atom on the other. The atomic connectivity of PtCO2H3− can be described as H2Pt(HCO2)−, where the platinum atom is bound to a formate moiety on one side and two hydrogen atoms on the other. Computational studies of the reaction pathway revealed that the hydrogenation of CO2 by PtH3− is highly energetically favorable.
