Tuning the degree of CO₂ activation by carbon doping Cu_n^- (n = 3-10) clusters: an IR spectroscopic study.

ABSTRACT: Copper clusters on carbide surfaces have shown a high catalytic activity towards methanol formation. To understand the interaction between CO₂ and the catalytically active sites during this process and the role that carbon atoms could play in this, they are modeled by copper clusters, with carbon atoms incorporated. The formed clusters Cu_nC_m^- (n = 3-10, m = 1-2) are reacted with CO₂ and investigated by IR multiple-photon dissociation (IR-MPD) spectroscopy to probe the degree of CO₂ activation. IR spectra for the reaction products [Cu_nC·CO₂]^-, (n = 6-10), and [Cu_nC₂·CO₂]^-, (n = 3-8) are compared
