| Abstract: | The electrochemical behavior of the nano TiO 2 electrode in different solutions were investigated by electrochemically transient methods, such as cyclic voltammetry, cyclic Osteryoung square wave voltammetry and linear potential sweep techniques as function of acid species, acidity, potential and temperature. The results showed that there were two pairs of reversible redox peaks, which were hardly affected by the acidity and anions of acids, and E r 1/2 in non oxidative acid solutions(H 2SO 4,HCl) was -0 52 V and -0 86 V, respectively. However, in oxidative acid solutions(H 2C 2O 4,HNO 3), there appeared a surface heterogeneous electrocatalytic behavior, but electrochemically half reversible behavior, in alkaline and neutral solutions(KOH,KCl). The nano TiO 2 electrode behaved sluggishly in anode scan range of -0 5~1 5 V. |
