Metal-CO interplay has been repeatedly emphasized to modify the structure or reactivity of a chemical species. A fundamental understanding on the nature of strongly bonded CO on noble metal catalysts is vital to prevent the catalysts from poisoning and then guide the advanced design. Herein, we identified the CO self-promoted oxidation by gas-phase cluster anions IrVO4-. Mass spectrometry experiment showed that the IrVO4- cluster can only anchor CO while product IrVO4CO- can oxidize CO and generate IrVO3CO-. The molecular-level origin of this positive effect of strongly bonded CO on noble metal has been rationalized by quantum-chemical calculations.
