dc.description.abstractThe kinetics of electrooxidation of HCOOH on Pt(100) via reactive intermediates was studied by using programmed step technique, which avoided successfully the interference of self-poisoning. A new data processing method was established based on the transform of integration of digital data recorded in electrochemical transient experiments, and the computer software developed for this method allowed us to obtain quantiatively, for the first time, the kinetics parameters of HCOOH oxidation on Pt(100) electrode. The results demonstrated that in a narrow potential range of 0.02 V to 0.15 V, the rate constant k(f) being varied from 9.510x10(-4) to 1.38x10(-2)cm.s(-1) and the relationship between In(k(f)) and E being a straight line. The transfer coefficient (beta) was calculated at 0.309, and the diffusion coefficient (D) of HCOOH in 5x10(-3) mol.L-1 HCOOH + 0.5 mol.L-1 H2SO4 solution was evaluated at 1.80x10(-5) cm(2).s(-1).zh_CN
