Abstract:

The adsorption of CO, on smooth Pt from solutions of 1 N . HClO sub 4 saturated with 1 atk. of CO at 40 C, was studied using anodic and cathodic galvanostatic transients. It was found that when a large anodic current is applied to the electrode, the potential increases rapidly to about 1.2 V vs. H2H in the same solution, falls to about 1.0 V, slowly starts to increase again, and finally becomes almost steady, probably due to O2 evolution. The charge passed in the various regions of this transient is insensitive to the current density in the range 2.3 to 147 macm2 and, also, to the starting potential in the range 0.1 to 0.8 V. Author
