Paramagnetic CO species adsorbed on the surface of scandium, yttrium, and lanthanum oxides
Abstract
The interaction of CO molecules with the surface of Sc, Y, and La oxides leads to the formation of paramagnetic polyatomic surface compounds containing two equivalent carbon atoms and lattice cations; a structure for the adsorbed (CO)2˙– radical anions which explains their high thermal stability and reactivity has been suggested.
