Formic Acid at Platinum, Rhodium, and Gold Electrodes

Chemisorption of Formic Acid at Platinum, Rhodium, and Gold Electrodes 

The electrooxidation of HCOOH at different electrodes has been thoroughly investigated due to the interest in this molecule as a model for an organic fuel. 

As mentioned for the CO species adsorbed from dissolved CO, the center of the band of simply bonded —CO varies linearly with the potential, with a positive rate of about 30 cm y-i (7o) jg certainly associated with 

The surface distribution of species adsorbed at rhodium also was investigated as a function of the bulk concentration of formic acid, the electrode
