Photoinduced Surface Dynamics of CO Adsorbed on a Platinum Electrode

Photoinduced Surface Dynamics of CO Adsorbed on a Platinum Electrode [Pg.84]

Adsorbed CO on a metal surface is one of the simplest adsorbates and has attracted significant interest within the areas of fundamental surface science, catalysis, and electrochemistry. An understanding of the oxidation mechanism of adsorbed CO is important to design and develop electrocatalysts for fuel cells [69-73] and the surface dynamics of adsorbed CO on electrode surfaces in electrolyte solutions is, therefore, very important. [Pg.84]

TR-SFG seems to be an ideal tool to study the surface dynamics of adsorbed CO at solid/liquid interfaces. Although there are several reports of TR-SFG studies on an electrode, they are only of investigations of vibrational relaxation lifetime by IR excitation [34, 65, 67]. [Pg.84]

In the present study, we investigated the SFG response of CO adsorbed on a Pt electrode surface in an electrolyte solution upon irradiation of intense visible pulses with time resolution of about 20 ps. [Pg.84]
