The dissociative adsorption and oxidation of formic acid on Pt(100) single crystal electrode were investigated by using elect heniical 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 d 0,25 V. Batted on results of TR-FTIRS, we concluded that the dissociative adsorption of HCOOH on Pt (100) can be a avoided by designing appropriate potential step program, winch is the basis of further studies, of the kinetics of direct oxidation of HCOOH into CO2 via reactive intermediates
