Electrocatalysis in anodic oxidation of organics with simultaneous oxygen evolution
Year: 1996
Type: article
Abstract: The electrochemical oxidation (or combustion) of organics with simultaneous oxygen evolution has been investigated using different electrode materials (Pt, Ti/IrO2, Ti/SnO2). 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 at the surface of which ˙OH radicals can be accumulated. 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.
