This investigation aims to study the experimental conditions for BaTiO3 electrodeposition along with PbO2 codeposition to get nano-PbO2 semiconducting electrode for electrocatalytic applications, here phenol as model compound. At first step, pretreatment of the Ti electrode and electrodepostion of barium focused in various steps in order to assure nano-structured surface and strong adherence. In second stage of experimental section explains preparation and utilization of two different electrochemical baths for electro-deposition of PbO2 on BaTiO3. Electrochemical technique of cyclic voltammetry helps to initial confirmation of PbO2. Further, SEM and XRD analyses firmly explain the morphological and composition PbO2 on BaTiO3. SEM and XRD results corroborate with the cyclic voltammetry results. The prepared electrode demonstrates its electrocatalytic activity on liquid pollutant phenol. At end, a discussion will be made for PbO2 on BaTiO3 effect and its stability with enhanced electrocatalytic removal of liquid pollutants. |
