Abstract The heterogeneous catalytic redox behaviour of a titanium dioxide coated titanium electrode surface was investigated with and without o-nitrophenol using cyclic voltammetry. A comparison of the cyclic voltammograms recorded in the absence and in the presence of o-nitrophenol confirmed the catalytic reduction of o-nitrophenol by the surface Ti4+/Ti3+ redox system present on the electrode surface. Preparative scale experiments were also carried out using a Ti/TiO2 electrode of large surface area and the redox behaviour of the electrode was confirmed by the isolation of o-aminophenol with high current efficiency and yield.
