In Situ Investigation

Infrared spectroelectrochemistry is the leading technique for in situ investigation of electrode - solution interfaces because it can both identify the species adsorbed at the metal/solution interface, and quantitatively follow their reaction and kinetic behavior. The unique capabilities of the method have been demonstrated by selective examples, including the identification of preferentially adsorbed species on single crystal surfaces of noble metals with hexagonal symmetry, and electrochemical oxidation of CO on bare and Pt-decorated single crystal Ru surfaces.

Adsorption Processes

The electrochemical behavior of platinum single crystal surfaces can be taken as a model response for the interpretation of the activity of heterogeneous electrodes. The cyclic voltammogram of a given platinum electrode can be considered a fingerprint characteristic of the distribution of sites on its surface. We start this review by providing some simple mathematical descriptions of the voltammetric response in the presence of adsorption processes. We then describe the voltammogram of platinum basal planes, followed by the response of stepped surfaces. The voltammogram of polycrystalline materials can be understood as a composition of the response of the different basal contributions. Further resolution in the discrimination of different surface sites can be achieved with the aid of surface modification using adatoms such as bismuth or germanium. The application of these ideas is exemplified with the consideration of real catalysts composed of platinum nanoparticles with preferential shapes.
