Structures of Metal Surfaces and Their Effects on Electrocatalysis

2 Structures of Metal Surfaces and Their Effects on Electrocatalysis 

In one sense, the reader might react to the section title by saying But we just found out about that in a previous section. It depends, we saw, on the bond strength to the metal of the intermediate radical, and there are two cases. 

These play between the ions in the surface, attractive and repulsive forces, and each kind will speed up or slow down the rate of the reaction if the elements we are discussing happen to be in an r.d.s. 

Of course, we are giving here an introduction to electrocatalysis. Adsorbed water, potential dependent with respect to its bonding to the surface, and orientation has not been touched upon, although, because everything is dependent upon the ubiquitous interatomic forces, the orientation of water on a surface affects the reaction rate. Active planes have not been brought into a specific mechanism, one, which experiment shows, is faster than other planes. And there is macroroughness that one can see, at least with a light microscope.
