摘要：

A very fast rate of CO transport at the Pt/electrolyte interface is reported. The mass transport was monitored by following the change of the electrode capacitance caused by H-ad displacement during carbon monoxide adsorption at potentials in the hydrogen adsorption region. A diffusion parameter was calculated assuming the validity of Fick's law. No dependence was found on the surface structure. (C) 2003 Elsevier Science B.V. All rights reserved.
