Abstract
The electrooxidation of formic acid on a Au film electrode in perchloric acid solution was investigated under controlled and continuous mass transport conditions, employing rapid scan in situ ATR-FTIR spectroscopy measurements with 25 ms time resolution. Comparison of the dynamics and the potential dependence of adsorbed spectator species (perchlorate) and of adsorbed bridge-bonded formates and evaluation of kinetic isotope effects on the reaction characteristics provides detailed information on the reaction mechanism.
