TI  - Cyclic voltammetry, FTIRS, and DEMS study of the electrooxidation of carbon 
      monoxide, formic acid, and methanol on cyanide-modified Pt(111) electrodes.

AB  - We have used cyanide-modified Pt(111) electrodes, in combination with cyclic 
      voltammetry (CV), Fourier transform infrared spectroscopy (FTIRS), and 
      differential electrochemical mass spectrometry (DEMS), to investigate the 
      oxidation of formic acid and methanol on Pt electrodes. Since CO is the poison 
      intermediate formed during the oxidation of both formic acid and methanol, we 
      have previously characterized the CO adlayer on cyanide-modified Pt(111) 
      electrodes. Poison formation on cyanide-modified Pt(111) is nearly completely 
      inhibited in the case of formic acid and methanol, the corresponding 
      electro-oxidation reaction proceeding, hence, exclusively through the reactive 
      intermediate pathway. These results suggest that, in the oxidation of formic acid 
      and methanol, the formation of adsorbed CO would require the presence of at least 
      three contiguous Pt atoms.
