Besides stability factor of PbO2, its wider potential window can make it as sensor field. It is known that Ba.PbO2 used as pervoskite material in semiconducting industry due to its enhanced electrode hardness and stability. Herein, the Ba.PbO2 electrode was electrochemically prepared on Ti substrate and utilized as NH3 sensor. At first, the electrodeposition was carried out at 65°C in 0.2 M H3BO3. Then, effect of current density and concentration of precursor of Barium and Lead were studied and optimized through cyclic voltammetry analysis. Further, the as prepared electrodes examined through SEM and XRD analyses. Finally, the prepared electrode was subjected to oxidize NH3, NH4Cl, and NH4CO3 through cyclic voltammetry technique in various pH solutions. |
