Abstract

We report the electrochemical modification of boron-doped diamond electrode surface with electrodeposited platinum microparticles of mean size of 193 nm +/- 107 nm. The activity of platinum microparticle modified boron-doped diamond (ca. 20 % platinum coverage) and platinum macro electrodes (100% platinum coverage) are measured and compared through lactic acid oxidation, selected because of the surface sensitive nature of the reaction. Significant differences are found with the modified BDD showing a markedly lower current density. (AU)
