The sustainability of the semiconducting materials are attributed to the various factors such as preparation condition, addition of metal ion ,polymers and so on. PbO2 is a semiconductor but behave like metal due to the property of non stoichiometric ratio of Pb and oxygen in the PbO2 composition. Thus, it is being still used as anodic material in real application such as Ozone production, and degradation of organic pollutants. Herein, Ceramic materials such as perovskite ABO3 type BaTiO3 planned to use to enhace the PbO2 sability. Among many deposition like sol-gel and thermal, electrochemical deposition adopted due to its strong adherence property. At first, BaTiO3 was deposited on Ti electrode at various current densities and coating time. In second layer, PbO2 was electrodeposited using different current densities and time. The prepared electrode characterized by the XRD, SEM and Cyclic voltammetry. Based on the BaTiO3 and PbO2 ratio, the electrode stability was analysed.The prepared material was stable around 750hrs. |
