dc.description.abstract
The HCOOH electrooxidation reaction (FAO) was experimentally studied on rhodium electrode using a flow cell in a 0.5-MHCOOH + 0.5-M H2SO4 solution. It was obtained the steady-state current-potential curve by chronoamperometry, whichdemonstrated that the FAO is verified in the potential region 0.45 < E/V < 0.70. The amount of adsorbed CO on the electrodesurface as a function of potential was quantified by stripping voltammetry after changing to a 0.50-M H2SO4 solution at closedelectric circuit. It was established that the spontaneous dissociative adsorption of HCOOH on rhodium produces irreversiblyadsorbed CO only for potential values E ≤ 0.40 V, and therefore, the FAO takes place in the absence of COad. These results canexplain the current-potential profiles obtained when the FAO is studied by cyclic voltammetry at different values of the potentialscan limits, where the behaviour is strongly influenced by the inhibition of reaction sites due to the adsorbed CO. A kineticmechanism for the FAO on rhodium is proposed on the basis of the results obtained, which are also in agreement with recentlypublished spectroscopic measurements.
