Abstract

Bridging the materials and pressure gaps : The adsorption of CO on ZnO surfaces becomes much stronger in the presence of preadsorbed CO2 (see picture; O red, Zn gray, C green). The increased strength of the interaction between CO and polycrystalline ZnO powder originates from the formation of tridentate carbonate species on the mixed-terminated (1010) surfaces, which increase the Lewis acidity of neighboring Zn2+ cations. (Figure Presented).
