Interaction of CO2 with a two-dimensional metal-organic network.
Extensive efforts have been directed toward identifying catalytic material composites for efficiently transforming CO2 into valuable chemicals. Within this longstanding scientific challenge, the investigation of model systems is of particular interest to gain fundamental insight into the relevant processes and to synergistically advance materials functionalities. Inspired by the ubiquitous presence of metal–organic active sites in the conversion of CO2, we study here the interaction of CO2 with a two-dimensional metal–organic network synthesized directly on a metal surface as a model system for this class of compounds. The impact of individual CO2 molecules is analyzed using scanning tunneling microscopy supported by density functional theory calculations.
