Anodic Oxidation of Organics on Oxide Anodes
The electrochemical oxidation (or combustion) of organics with simultaneous oxygen evolution has been investigated using different oxide electrodes. A simplified mechanism for the electrochemical oxidation of organics is presented, according to which selective oxidation occurs with oxide anodes (MOx) for which the formation of higher oxides (e.g.: MOX+1,) is possible. Combustion occurs at electrodes with oxidatively saturated surface. Detection of OH radicals formed by water discharge at different anodes using N,N dimethyl-p-nitrosoaniline (RNO) as a spin trap and preparative electrolysis confirmed the proposed mechanism.
