CO2 Activation by ZnO through the Formation of an Unusual Tridentate Surface Carbonate


  • This research was carried out under the funding of the German Research Foundation (DFG) within SFB 558 “Metal-Substrate Interactions in Heterogeneous Catalysis”. Computational resources were provided by HLRS (Stuttgart) and Bovilab@RUB (Bochum). H.Q. thanks the IMPRS of SurMat for a research grant.

Greenhouse gas “al dente”: Exposure of the nonpolar ZnO(10equation image0) surface to CO2 at 95 K leads to the formation of an unusual tridentate carbonate species (see picture; C green, O red, Zn gray). Use of several experimental techniques (for example, high-resolution electron energy loss spectroscopy (HREELS)) and theoretical calculations provides insight into the activation of CO2 on the surface.
