Carbon monoxide adsorption on anatase TiO2 nanoparticles

Graphical abstract of the article:"On the Simple Complexity of Carbon Monoxide on Oxide Surfaces: Facet-Specific Donation and Backdonation Effects Revealed on TiO2 Anatase Nanoparticles"ChemPhysChem. doi:10.1002/cphc.201600284IR and modeling studies on TiO2 nanoparticles reveal that the stretching frequency of adsorbed CO results from a synergic donation/backdonation mechanism, by which the surface oxygen anions act as electron donors even if not directly bonded to the adsorbate.This item also contains an additional figure of the Ti sites and a simplified representation of the Ti-CO bonding mechanism. Both images were created for a blog post. Further material can be found at the links below. The last link refers to the above-mentioned blog post explaining and commenting the findings of the article.
