Inducing or steering a chemical reaction by controlling the charge is a key aspect in catalysis. The charge flow at an oxide–metal interface is of paramount importance for a successful catalytic reaction. Scanning probe investigations of such an interface reveal a two‐dimensional Au particle of one monolayer height and a diameter of 6 nm residing on a magnesium oxide film, the same Au raft after adsorption of CO 2 at its rim, the high localization of electron density at the negatively charged cluster rim, and the change in energy of the first quantum well states on CO 2 adsorption.
