Oxidation of organics by intermediates of water discharge on IrO2 and synthetic diamond anodes

Christos Comninellis, György Foti

IrO2 and boron-doped diamond electrodes were tested by preparative electrolysis of simple model compds. in acid medium. In oxidn. reactions of more complex mechanism than simple electron transfer, these electrodes are active only at potentials of simultane ...

Anodic oxidation of organics on synthetic diamond thin-film electrodes

Christos Comninellis

The electrochem. oxidns. of some org. compds. have shown that only reactions involving simple electron transfer are active on diamond electrodes in the potential region of water stability. For more complex reactions, diamond electrodes show no electrocatal ...
