DIFFUSION-LIMITED PROCESSES ON FRACTAL SURFACES GENERATED AS A SET OFSCALED WALSH-FUNCTIONS

The Mote Carlo technique was used for modelling mass transport to frac tal electrode surfaces under conditions of a potentiostatic pulse and linear scan voltammetry. Fractal surfaces of different fractal dimensi on D were constructed using the Walsh-Hadamard transform. The effects of surface geometry on the form of the current response and long-time cut-off are discussed with respect to the validity of diagnostic proce dures used for the electrode kinetics on smooth electrodes.
