CO₂ activation by copper oxide clusters: size, composition, and charge state dependence.

ABSTRACT: The interaction of CO₂ with copper oxide clusters of different size, composition, and charge is investigated via infrared multiple-photon dissociation (IR-MPD) spectroscopy and density functional theory (DFT) calculations. Laser ablation of a copper target in the presence of an O₂/He mixture leads to the preferred formation of oxygen-rich copper oxide cluster cations, Cu_xO_y⁺ (y > x; x ≤ 8), while the anionic cluster distribution is dominated by stoichiometric (x = y) and oxygen-deficient (y < x; x ≤ 8) species. Subsequent reaction of the clusters with CO₂ in a flow tube reactor results in the preferred formation of near-stoichiometric Cu_x
