Electrocatalytic reactivity

In this chapter, we have described modern electrochemical surface science and catalysis and shown fundamental correlations between the structure, bonding, composition and electrocatalytic reactivity at the interface. 

The primaiy emphasis in this review article is to showcase the use of LEISS to examine the outermost layers of Pt-Co alloys in order to correlate interfacial composition with electrocatalytic reactivity towards oxygen reduction. In some instances, it is desirable to compare the properties of the outermost layer with those of the (near-surface) bulk an example is when it becomes imperative to explain the unique stability the alloyed Co under anodic-oxidation potentials. In such cases. X-ray photoelectron spectroscopy and temperature-programmed desorption may be employed since both methods are also able to generate information on the electronic (binding-energy shift measurements by XPS) and thermochemical (adsorption enthalpy determinations by TPD) properties at the sub-surface. However, an in-depth discourse on these and related aspects was not intended to be part of this review article. 

Catalysis and Electrocatalysis at Nanoparticle Surfaces is a modern, authoritative treatise that provides comprehensive coverage of recent advances in nanoscale catalytic and electrocatalytic reactivity. It is a new reference on catalytic and electrochemical nanotechnology, surface science, and theoretical modeling at the graduate level.

There should be increased study of bimetalUc surfaces to establish stmctural trends in surface behavior across the periodic table and the correlation between these trends and electrocatalytic reactivity.
