Abstract : The effect of CO2 on the oxidation of H atoms chemisorbed on a Pt electrode was examined with potentiostatic and transient galvanostatic techniques. The results indicate that CO2 is not reduced, but that Had oxidation is inhibited by CO2, or possibly HCO3(-). Under these conditions the inhibited or blocked Had is stable at potentials negative to 0.300 V (vs N.H.E.). Dissociation of HCOOH to Had and CO2 may inhibit the further oxidation of HCOOH by a similar blocking mechanism. (Author)
