摘要：

Adsorption of CO on a Pt(110)-(1 x 1) surface in a Na2CO3 solution produces a structural surface modification as proved by the change of the profile and electric charge of the "voltammetric" curve of the adsorption-desorption hydrogen process. The surface modification is clearly voltammetrically perceptible for a coverage of CO greater-than-or-equal-to 0.25.
