The electrocatalytic oxidation of formic acid on Pt(100)/Sb electrodes of different coverage of Sb was investigated by using electrochemical techniques and in situ time-resolve FTIRS. The results demonstrated that the diessociative adsorption of formic acid was inhibited by the presence of Sb-ad on Pt(100) surface,as a consequence HCOOH can be oxidized directly into COL via reactive intermediates. The rate of oxidation of formic acid varied with the coverage of Sb-ad. It was revealed that at a Sb-ad coverage of 0.24 the Pt(100)/ Sb electrode exhibited the highest electrocatalytic activity for HCOOH oxidation.
