Ru(NH 3 ) 6 at a Kel-F=gold composite electrode. Points are experimental data, the solid
line is the least-squares ®t to theory. Dashed lines are theoretical Cottrell plots for a
macroelectrode with active area equal to the active area of the composite (curve a) and to
the geometric area of the composite (curve b). (Reproduced with permission from reference
