FIGURE 13.8 Real periodic electrocatalyst smooth or rough electrode surfaces. A smooth catalyst exhibits no preferential growth along a single axis, while the rough periodic surface shows a (x, y) plane preferential crystallization. 

In the example shown in Figure 13.8, we can see that the preferential surface roughness occurs along the (x, v) plane. This type of periodical behavior can be modeled by a mathematical expression for crystal growth, G(x,y). On a first approximation, we can consider that along x the growth of the catalyst is constant so that...
