| Abstract | : | Titanium-lead dioxide electrode (Ti/PbO2) has been synthesized by the method of anodic electrodeposition from alkaline solutions with a concentration variation of NaF (0.0048-0.0238 M). The results indicated that the presence of F- ions affects the rate of formation of PbO2 which may impact on its properties. SEM analysis showed that the PbO2 film has nanorod-shaped surface morphology with a diameter of 50 nm and a length of 500 nm. X-Ray diffraction study showed that the material was composed of a mixture of a-phase (021; 200; 311) and b-phase (002; 211; 220; 112) whose intensity decreases with an increase on the addition of NaF. Cyclic voltametry results showed a correlation of the electrocatalytic activities with the intensity of phase. The electrocatalytic performance of PbO2 is more likely to be affected by the b-phase (221 and 220) than by the a-phase (021). In other words, the electrocatalytic activity of PbO2 is influenced more by the surface area of the conductivity properties. |
