Abstract:
The observed isotopic effect in CO2 + Hads reaction showed that at 0.05 V the rate determining step is formation whereas at 0.2 V the reorientation of adsorbed intermediate: is probably the slowest step of reaction. The oxidation of adsorbed product is slower in D2SO4 than H2SO4 solution like the surface oxidation of platinum. The rate determining step of COOHads oxidation is a reaction with OHads.
