| Abstract: | The high active Ti/nano-TiO_2-Pt electrode is prepared by electrochemical synthesis and electrodeposition. The electrochemical behavior of the TiO_2/nano membrane electrode, Pt electrode and Ti/nano-TiO_2-Pt electrode in H_2SO_4 solution have been studied by cyclic voltammetry. The property of Ti/nano-TiO_2-Pt electrode in oxidation of Mn~(2 ) to Mn~(3 ) is also studied. The results show that the Ti/nano-Pt electrode has high catalytic activity in Mn~(2 ) oxidation of 1.28 V(vs. SCE) oxidation potential peak, 0.12 V negative shifted as compared with that occurrs on Pt electrode. The oxygen-releasing potential is 1.4 V, about 0.08 V higher than that of Pt electrode. The electro-catalysis property of Ti/nano-TiO_2-Pt electrode is better than that of the Pt electrode and Ti/nano electrode, it gives a average current efficiency more than 90% in non-homogeneous electrolytical oxidation of Mn~(2 ) to Mn~(3 ). |
