Sonoelectrochemistry at platinum and boron-doped diamond electrodes: achieving 'fast mass transport' for 'slow diffusers'

Katherine B. Holt; Javier del Campo; John S. Foord; Richard G. Compton; Frank Marken

Abstract It is demonstrated for electrochemical processes in aqueous solution enhanced by ultrasound from a glass-horn transducer (24 kHz, 8 Wxa0cm−2) that the mass transport limited current is essentially independent of the diffusion coefficient. An explanation is proposed for this phenomenon, which allows, at low ultrasound power, considerable enhancements of the mass transport of ‘slow diffusers’ with small D, to be achieved via interfacial cavitation. An application of this effect in the anodic destruction of an aqueous Procion Blue dye solution at boron-doped diamond electrodes is discussed.

Diffusional protection of electrode surfaces using regular arrays of immobilised droplets: overcoming interferences in electroanalysis

Andrew O. Simm; Olga Ordeig; Javier del Campo; Francesc Xavier Muñoz; Richard G. Compton

Regular arrays of ca. micron sized droplets on a gold electrode surface can block diffusion to the electrode surface of one metal ion (which binds with the material in the droplet) whilst having no significant effect on another (which does not), so allowing interference effects in electroanalysis to be eliminated.
