Cannonball run : Preparation of CO 2 has been achieved with CO and O 2 coadsorbed onto a Cu(111) surface by illumination with 40 fs pulses of laser light at 400 nm. The hot adatom mechanism that follows O 2 dissociation leads to a cannonball trajectory of the product molecules and thus escape of CO 2 from the reactant site to the bare terrace (see figure). It was thus demonstrated that non‐adiabatic heterogeneous catalysis may be followed in real space.
