IR spectroscopic characterization of the co-adsorption of CO₂ and H₂ onto cationic Cu_n⁺ clusters.

ABSTRACT: To understand elementary reaction steps in the hydrogenation of CO₂ over copper-based catalysts, we experimentally study the adsorption of CO₂ and H₂ onto cationic Cu_n⁺ clusters. For this, we react Cu_n⁺ clusters formed by laser ablation with a mixture of H₂ and CO₂ in a flow tube-type reaction channel and characterize the products formed by IR multiple-photon dissociation spectroscopy employing the IR free-electron laser FELICE. We analyze the spectra by comparing them to literature spectra of Cu_n⁺ clusters reacted with H₂ and with new spectra of Cu_n⁺ clusters reacted with CO₂. The latter indicate th
