Kinetics of Irreversible Reactions on Platinum Single Crystal Electrodes
Abstract:
The dissociative adsorption and oxidation of formic acid on Pt(100) single crystal electrode were investigated by using electrochemical techniques and in situ time resolved FTIR spectroscopy (TR-FTIRS). The results demonstrated that the distribution of the rate of dissociative adsorption of HCOOH on Pt(100) versus electrode potential yields a volcanic relationship between -0.25 and 0.25 V. Based on results of TR-FTIRS, we concluded that the dissociative adsorption of HCOOH on Pt(100) can be avoided by designing appropriate potential step program, which is the basis of further studies of the kinetics of direct oxidation of HCOOH into CO2 via reactive intermediates.
